FIELD OF THE INVENTION

[0001] The present invention relates to a mosaic element adapted to engage with a plurality of further mosaic elements to form a mosaic. More specifically, in some preferred embodiments, each further mosaic element has a shape at least substantially similar to the shape of the mosaic element. The present invention also relates to a kit and a method of forming a mosaic. More specifically for the method, the mosaic element and the plurality of further mosaic elements are engaged so as to form the mosaic.

BACKGROUND

[0002J It is known that mosaics come in many forms, are created from many different materials, and are used for a multitude of purposes. Mosaics generally take the form of artworks, however they have also been used in and for interior wall and floor coverings. Materials commonly used to construct mosaics include plaster, ceramics, wood, tiles, and glass, chosen depending on purpose. Both the size of the individual pieces which make up the mosaic, as well as the mosaic as a whole, vary independently, again depending on the purpose of the mosaic.

[0003] Current mosaics are constructed from many separate pieces, or mosaic elements, which are individually, and permanently affixed, or adhered, to a desired surface. Whether the mosaic be in a larger form used for interior design, such as wall and floor coverings, or artistic decoration of surfaces, such as murals, cement, plaster and other permanent setting, binding agents are often employed to have the mosaic elements irreversibly fixed to the surface and one another.

[0004] Commonly the individual mosaic elements which make up the mosaic are of a single colour. Although a mosaic element will generally also have a pre-set pattern of its own, it is not also suitable for use as a panel or adapted to have an image applied to it by a person or machine, which image is conceived and/or selected by that person or machine, with or without particular regard to an image applied to a further mosaic element by the same or another personal machine, and with or without particular intention to enable a mosaic formed by the two images adjacent one another to necessarily form an overall coherent or identifiable mosaic across the two or more mosaic elements when arranged adjacent to one another. [0005] Due to current mosaics having their mosaic elements being permanently fixed, it is not possible to rearrange or easily relocate or move a mosaic, whether they be in the form of a wall or floor covering, or artistic work. However, without the use of permanent setting biding agents, mosaic elements will disassociate from one another.

[0006] Furthermore, typical mosaic elements are not used in the context of forming a puzzle. A puzzle is a game, problem, or toy that tests a person's ingenuity or knowledge. In a puzzle, the solver is expected to put pieces together in a logical way, in order to arrive at the correct or fun solution of the puzzle. Puzzles have long been popular for amusement and entertainment. Traditional puzzles have a number of interlocking pieces which may be fitted together to form a complete pictorial representation, for example, of a photograph or artistic rendering of a landscape, still life or another image. The number of pieces and the complexity of the pictorial image may be varied to make assembling the puzzle more or less difficult, depending on the age and ability of the intended player. Likewise, the image or the pattern may be selected to appeal to the age or interests of the player.

[0007] In some educational settings, it is desirable to add an element of fun and entertainment to engage and retain the student's interest, for example, in connection with learning to read or exploring a concept of any subject matter. Games such as puzzles add this element and encourage learning. Even older children and adults can benefit firom and enjoy such puzzles. However, the current puzzle system lacks effectiveness and efficiency.

[0008] Also, typical puzzle systems do not present a mechanism for students to learn from one another, including because they are not adapted to have an image applied to them by the students. The ability for students to apply an image to a mosaic element can enable them to learn from one another. For example, the ability for students to each apply in image to a mosaic element can enable the students to together tell a story about something, such as their collective life history or culture. The interconnections between their respective life histories or cultures can be brought to light by assembly of the mosaic by engaging each mosaic element. In turn, that process can assist with educating the students, for example, in respect of reconciliation such as amongst indigenous and nonindigenous populations.

[0009] The present invention is directed to a mosaic element, kit and method for forming a mosaic that seek to overcome or ameliorate some of the shortcomings described above.

[0010] Any reference to or discussion of any document, act or item of knowledge in this specification is included solely for the purpose of providing a context for the present invention. It is not suggested or represented that any of these matters or any combination thereof, formed at the priority date, part of the common general knowledge, or was known to be relevant to attempt to solve any problem with which this specification is concerned.

BRIEF SUMMARY OF THE INVENTION

[0011] According to a first aspect, the present invention provides a mosaic element having an even number of sides greater than two sides and a first shape that is at least substantially symmetrical, wherein

each side of a first set of sides comprising half of the mosaic element sides, includes at least one projection that does not form part of the first shape,

each side of a second set of sides comprising the other half of the mosaic element sides, includes at least one recess that does not form part of the first shape,

wherein the at least one projection is adapted to engage at least one recess in a side of a second mosaic element or in a side of an at least one further mosaic element.

[0012] In some embodiments, each projection is a tab-like feature that extends outwardly from the side having that projection. In some such and other embodiments, each recess is a carve out-type feature that extends inwardly into the side having that recess.

[0013] In some preferred embodiments, the at least one projection has a shape that at least substantially corresponds to a shape of an at least one recess in a side of a second mosaic element and or in a side of a further mosaic element. Preferably, the shape of each projection corresponds to the shape of each recess.

[0014] Preferably, the first set of sides comprises sides that are adjacent to one another.

[0015] In yet further preferred and alternative embodiments, the first set of sides comprises sides that are at least substantially parallel to one another. Preferably, the first set of sides comprises sides that are parallel to one another.

[0016] In some embodiments, the at least one projection includes at least one sub projection having a shape that at least substantially corresponds to a shape of an at least one sub-recess in a recess in a side of a second mosaic element and or to a shape of an at least one sub-recess in a recess in a side of a further mosaic element.

[0017] According to some such and other embodiments, the at least one projection includes at least one sub-recess having a shape that at least substantially corresponds to a shape of an at least one sub-projection in a recess in a side of a second mosaic element and or to a shape of an at least one sub-projection in a recess in a side of a further mosaic element.

[0018] In yet still further of such and other embodiments, the at least one recess includes at least one sub-projection having a shape that at least substantially corresponds to a shape of an at least one sub-recess in a projection in a side of a second mosaic element and or to a shape of an at least one sub-recess in a projection in a side of a further mosaic element.

[00191 Preferably or alternatively, the at least one recess includes at least one subrecess having a shape that at least substantially corresponds to a shape of an at least one sub projection in a projection in a side of a second mosaic element and or to a shape of an at least one sub -projection in a projection in a side of a further mosaic element.

[00201 I ⁿ some embodiments, each sub-projection is a tab-like feature that extends outwardly from the side having that projection. In some such and other embodiments, each recess is a carve out-type feature that extends inwardly into the side having that recess.

[0021 J In yet still some preferred and alternative embodiments, a sub-projection may further include a sub-sub-projection or a sub-recess, and a sub-recess may further include a sub-sub-recess or a sub-projection. Persons skilled in the art would be able to appreciate the possible permutations and combinations for projections, recesses, sub-projections, sub recesses, sub-sub-projections, sub-sub-recesses and so on. The balance of the patent specification focuses on embodiments with projections, recesses, sub -projections and subrecesses.

[0022] In some preferred embodiments, when the at least one projection, with or without a sub-projection and or a sub-recess, in a side of the mosaic element is engaged with an at least one recess, correspondingly with or without a sub-projection and or a sub-recess, in a side of the second mosaic element or with an at least one recess, correspondingly with or without a sub-projection and or a sub-recess, in a side of a further mosaic element, a first plane of the mosaic element at least substantially aligns with a second plane of the second mosaic element or substantially aligns with a further plane of a further mosaic element, and the substantially aligned first plane, second plane, and or further plane, together form an engagement plane.

[0023] Some such and other preferred and alternative embodiments provide that when the at least one recess, with or without a sub-projection and or a sub-recess, in a side of the mosaic element is engaged with an at least one projection, correspondingly with or without a sub-projection and or a sub-recess, in a side of the second mosaic element and or with an at least one projection, correspondingly with or without a sub-projection and or a sub-recess, in a side of a further mosaic element, a first plane of the mosaic element at least substantially aligns with a second plane of the second mosaic element or substantially aligns with a further plane of a further mosaic element, and the substantially aligned first plane, second plane, and or further plane, together form an engagement plane. [0024] Preferably, the first plane aligns with the second plane and or the further plane, in such embodiments, the engagement plane is preferably a flat plane.

[0025] Yet still further of such and other preferred and alternative embodiments provide that when the first plane forms part of the engagement plane, the mosaic element is at least substantially inhibited from disassociating from engagement with the second mosaic element and or from disassociating from engagement with a further mosaic element.

[0026] In some embodiments, the inhibition of engagement or disassociation is inhibition in the engagement plane. In some such embodiments, the inhibition of engagement or disassociation occurs due to the corresponding shapes of the projection and recess, with or without correspondingly shaped sub-projections and sub-recesses. Preferably, the inhibition of engagement or disassociation in such embodiments is not an inhibition in circumstances where the mosaic elements are caused to each be moved in at least slightly different directions out of the engagement plane, for example, when the mosaic elements are twisted relative to one another.

[0027] Preferably, when the first plane forms part of the engagement plane, a face of the mosaic element and a second face of the second mosaic element, and or a further face of a further mosaic element, together depict a mosaic.

[0028] In some embodiments, the mosaic depicted is a pattern or a collage. In some such embodiments, the pattern is a repeated pattern and or an identifiable image. In an embodiment where the mosaic depicted is a pattern, or even a repeating pattern, each of the mosaic elements forming the mosaic may depict, on a face, a self-contained pattern which is repeated across all the mosaic elements. Alternatively, each of the mosaic elements forming the mosaic may not have a self-contained pattern, and instead each of the mosaic elements depicting, on a face, a smaller portion of an overall pattern, where the overall pattern will become apparent when the mosaic elements are engaged with one another so as to form that pattern.

[0029] In an embodiment where the mosaic depicted is an identifiable image, each of the mosaic elements forming the mosaic have, on a face, either a smaller portion of the overall image that is identifiable, or may have an image which is contained on the face of each mosaic element. In embodiments where the image is contained on the face of the mosaic element, the image contained may still form part of a more complete identifiable image.

[0030] In embodiments where in the mosaic is a collage, the collage is a collection or combination of unconnected images. In an embodiment where the mosaic depicted is a collage, then each of the mosaic elements forming the mosaic may have an image contained to the face of each mosaic element, and may not be required to form a larger image when arranged as a mosaic. In some such embodiments, the collage comprises a plurality of mosaic elements, with each mosaic element including on its face and image applied by a personal machine that is intended to reflect a person’s or group of persons’ history or culture. In preferred and alternative of such and body mints, when the mosaic elements are engaged with one another, the collage that is formed represents a portrayal of adjacent personal histories or cultures adjacent one another. In some such embodiments, the collage aids in education concerning reconciliation of indigenous and nonindigenous peoples.

[0031] Preferably, a person or machine, or different people and or different machines, cause one or more images to be applied to the face of the mosaic element and or to the second face of the second mosaic element and or to the further face of the further mosaic element.

[0032] In some preferred embodiments, interposed between the first shape and one or more of each projection is a frangible join. Preferably, breakage of a frangible join permits removal of a projection, with or without a sub-projection and or a sub-recess, which removed projection is engageable with a corresponding recess, correspondingly with or without a subprojection and or a sub-recess.

[0033] Preferred embodiments of the frangible join can be formed by any suitable means that would enable each projection to be removed from the side of the mosaic element. The frangible join can, for example, be formed of a plurality of perforations or be formed of a snap join or be formed by atearable join. Persons skilled in the art would be able to determine a suitable form of join that is frangible, including taking account of the materials used to form the mosaic element.

[0034] In some preferred embodiments, the relative symmetry of the first shape is such that each half of the first shape, when bisected along and axis of symmetry, is substantially identical or identical to the other half. In embodiments where the first shape is substantially symmetrical, when bisected along and axis of symmetry, a substantial majority of the areas of each half of the shape are congruent. In further alternatives, the symmetry of the first shape is such that each half of the mosaic element, when bisected along the axis of symmetry, the halves of the shape are of substantially similar dimensions.

[0035] Preferably the number of sides of the substantially symmetrical mosaic element is four sides, each of which is substantially the same length. In the alternative, the mosaic element has either six, eight or ten sides, preferably with each side being of the substantially the same or the same length. The invention contemplates a mosaic element having any even number of sides greater than two sides. [0036] In a further alternative, in an embodiment where the number of sides of the mosaic element is four sides, each parallel side is substantially the same length as its opposite counterpart side. In the alternative, where the mosaic element has six, eight or ten sides, each set of parallel sides are at least substantially of the same length.

[0037] Preferably, the second mosaic element and or the further mosaic element all have substantially identical dimensions as well as the same number and location of projections, recesses, sub-projections and sub-recesses. Alternatively, the second mosaic element and or the further mosaic are not substantially identical with the mosaic element or with one another.

[0038] In some embodiments, the mosaic element, the second mosaic element and the further mosaic element/s each have only a single projection and only a single recess. In other further alternatives, the mosaic element, the second mosaic element and the further mosaic element/s each have three or more projections, and an equal number of recesses.

[0039] In a preferred embodiment, the first shape is symmetrical with four sides, the first set of sides are adjacent to one another and each includes a single projection with or without sub-projections and or sub-recesses, and the second set of sides comprise the balance of adjacent sides in each side in the second set of sides includes a single recess with or without sub-projections and or sub-recesses. In some such preferred embodiments the second mosaic element and any further mosaic element is identical to the mosaic element.

[0040] Preferably each projection and recess are at least substantially the same shape, and each recess has the same dimensions as each corresponding projection. Alternatively the dimensions of a recess is slightly larger than that of the corresponding projection, such that there is a not significant amount of empty space between the recess and the projection when they are engaged in accordance with the invention.

[0041] Preferably, a projection is adapted to engage any recess. Alternatively, a projection is adapted to engage at least one recess on either the second mosaic element or a further mosaic element.

[0042] In a preferred embodiment of the invention the sides of the mosaic element are straight. In a further alternative embodiment, the sides are at least substantially straight. Alternatively, each side is not straight but does not have significant inflections and variations that would otherwise inhibit engagement of the mosaic element, the second mosaic element and or any further mosaic element.

[0043] In an alternate embodiment of the invention wherein the first set of sides comprises sides that are at least substantially parallel to one another. Preferably the set of sides are exactly parallel. Alternatively the set of sides are substantially parallel while not inhibiting the mosaic element, the second mosaic element and any further mosaic element from engaging.

Preferably each projection has more than one sub-projection, and each recess has more than one sub-recess. Alternatively each projection has one sub-projection and each recess has one sub-recess.

[0045] In a preferred embodiment of the invention wherein the at least one first projection includes the at least one sub-recess. Preferably each projection has more than one sub-projection and sub-recess. Alternatively each projection as one sub-projection and one sub-recess. In another alternative each projection has an equal number of sub projections and sub-recesses.

[0046] In a preferred embodiment of the invention wherein the first recess further includes at least one sub-projection. Preferably each recess has more than one sub-projection and sub-recess. Alternatively each recess as one sub-projection and one sub-recess. In another alternative each recess has an equal number of sub-projections and sub-recesses to a corresponding projection with a corresponding number of sub -projections and sub-recesses.

[0047] In a preferred embodiment of the invention wherein the sub -projection corresponds in shape to the sub-recess. Preferably the dimensions of the sub-recess are at least substantially identical to those of a corresponding sub-projection. Alternatively the dimensions of a sub-recess are slightly larger than those of a corresponding sub-projection [0048] In a preferred embodiment of the invention including a mounting bracket on a face of the mosaic element, the second mosaic element, and/or the further mosaic element. In some embodiments of the invention, the bracket has screw threads. In other such embodiments of the invention the bracket is such that it allows the mosaic element to hang from a rail. Person skilled in the art will appreciate the wide array of possible means for a mounting bracket that would enable the mosaic element to be mounted on a surface.

[0049] In a preferred embodiment of the invention wherein a projection is separated by breakage of a frangible join from a side of the mosaic element or from a side of the second mosaic element, or from a side of a further mosaic element, that separated projection, with or without sub-projections or sub-recesses, can be engaged with a recess, correspondingly with or without sub-projections or sub-recesses, where no other mosaic element will be engaged. For example, the separated projection may be engaged with a recess on an outer perimeter of a mosaic formed by a plurality of mosaic elements so that the outer perimeter at that point of engagement is flat rather than having a recess. In some such embodiments separation of the projection occurs also at an outer perimeter of the mosaic formed by a plurality of mosaic elements. In such embodiments, the outer perimeter at that point of separation is flat rather than having a projection.

[0050J In a preferred further embodiment of the invention the mosaic element, the second mosaic element and any further mosaic element are all of the same thickness. In some alternate embodiments of the invention, the thickness of mosaic elements may be variously in part the same, and in part different, to one another.

[0053] According to fourth aspect, the present invention provides a kit for forming a mosaic comprising a plurality of mosaic elements according to any one of the first, second, or third aspects of the invention. [0054] In some preferred embodiments, the number of mosaic elements supplied with the kit is preferably determined by reference to the overall size that the formed mosaic is intended to have. In some such embodiments, a length of the intended size of the formed mosaic is preferably at least substantially equal to a multiple of the longest distance spanning the first shape, and a breath of the intended size of the formed mosaic is preferably at least substantially equal to a multiple of the widest distance spanning the first shape.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0070] Preferred embodiments of the invention will now be described with reference to the accompanying drawings.

[0071] Figs. 1A and I B, show one preferred embodiment of mosaic element 100 that is suitable for forming a mosaic according to the invention, in front plan and front-top right isometric perspective views, respectively.

[0072] In a preferred embodiment, mosaic element 100 is substantially symmetrical made up of 4 sides. It has a front face 105. Projection 101 extends from a first side 400 of mosaic element 100 and a second projection (not numbered) extends from an adjacent side 401 of mosaic element 100. Recess 102 is formed in a third side 402 of mosaic element 100 and a second recess (not numbered) is formed in an adjacent side, being the fourth side 403 of mosaic element 100.

[0073] The first and second sides (400 and 401) together comprise a first set of sides for mosaic element 100 and the third and fourth sides (402 and 403) together comprise a second set of sides for mosaic element 100. Accordingly, in the embodiment of mosaic element 100 depicted in the figures, the first set of sides comprise sides (400 and 401) that are adjacent to one another.

[0074] Projection 101 and the other projection (not numbered) are, in this preferred embodiment, identically shaped but face opposite directions. Projection 101 includes sub recess 103 and sub-projection 104. It also includes other sub-recesses (not numbered) and other sub-projections (not numbered).

[0075] Recess 102 and the other recess (not numbered) are, in this preferred embodiment, identically shaped but face opposite directions. As illustrated, the shape of recess 102 and of the other recess correspond to the shape of projection 101 and the other projection (not numbered), respectively. Recess 102 includes sub-projection 103a and sub-recess 104a. It also includes other sub-recesses (not numbered) and other sub-projections (not numbered). Sub-projection 103a corresponds in shape to sub-recess 103 and sub-recess 104a corresponds in shape to sub-projection 104. Similarly, in this depicted embodiment, the balance of sub- recesses (not numbered) and sub-projections (not numbered) in recess 102 have corresponding sub-projections (not numbered) and sub-recesses (not numbered) in projection 101.

[00761 A frangible join 106 is depicted as interposed between projection 101 and first side 400 of mosaic element 100. In preferred embodiments, frangible join 106 permits projection 101 to be removed from first side 400.

[0077J A personal machine can apply an image to front face 105 which image will ultimately form part of a mosaic when each mosaic element is engaged in the engagement plane (not shown).

[0078] Figs. 2A and 2B show the preferred embodiment of mosaic element 100 shown in Figs 1 A and I B from a back plan and back-top right isometric perspective view, respectively. Mosaic element 100 has a back face 200 that opposes the front face 105. Bracket 201 on back face 200 is depicted illustratively only in these Figures to show a potential position and potential shape for bracket 201 on back face 200. Bracket 201 is intended to enable mosaic element 100 to be attached to a surface, such as a wall, ceiling, or floor.

[0079] In some cases, a correspondingly shaped receiving bracket to the shape of bracket 201 may need to be secured to the surface so that bracket 201 can engage with the receiving bracket. Persons skilled in the art can determine a suitable securing system to secure a mosaic element 100 to a surface. Not all embodiments of a mosaic element according to the invention include bracket 201. In suitable circumstances, which would be understood by persons skilled in the art, mosaic on at 100 could be secured to a surface using adhesives or other means.

[0080] Fig. 3 shows a plurality of mosaic elements 100 according to the preferred embodiment depicted in Figs 1 A, I B, 2A and 2B.

[0081] Dotted rectangle 300 highlights engagement of a projection (with subprojections and sub-recesses) on a side of mosaic element 100 with a correspondingly shaped recess (with corresponding sub-recesses and sub-projections) in a side of a second mosaic element 100. Also illustrated, though not highlighted by any reference, is a projection (with sub-projections and sub-recesses) on a side of a further mosaic element 100 engaging with a correspondingly shaped recess (with corresponding sub-recesses and sub-projections) in a side of the second mosaic element 100.

[0082] Another aspect of the present invention is directed to a kit for forming a mosaic comprising a plurality of mosaic elements 100. [0083] Another aspect of the present invention is directed to a method of forming a mosaic using two or more mosaic elements 100, or using a kit as described above, the method comprising:

engaging a mosaic element 100 with the second mosaic element 100 and or a further mosaic element 100, by

causing the at least one projection 101 , with or without a sub-projection 104 or a sub-recess 103 to engage with a recess 102, correspondingly with or without a sub-recess 104a or a sub-projection 103 a, in a side of the second mosaic element (as depicted in dotted rectangle 300), and or to engage with a recess 102, correspondingly with or without a sub recess 104a or a sub-projection 103a, in a side of a further mosaic element 100, and or

causing the at least one recess 102, with or without a sub-recess 104a or a subprojection 103a to engage with a projection 101, correspondingly with or without a sub projection 104 or a sub-recess 103 in a side of the second mosaic element 100, and or to engage with a projection 101 , correspondingly with or without a sub-projection 103a or a sub-recess 104a, in a side of a further mosaic element 100,

such that a first plane (not identified by reference numeral) of the mosaic element 100 at least substantially aligns with a second plane (not identified by reference numeral) of the second mosaic element 100 or substantially aligns with a further plane (not identified by reference numeral) of a further mosaic element 100, and the substantially aligned first plane, second plane, and or further plane, together form an engagement plane (not identified by reference numeral), and

a face (the front face 105 acts as this face) of the mosaic element 100 and a second face (this would be equivalent to front face 105 on the second mosaic element) of the second mosaic element 100, and or a further face (this would be equivalent to front face 105 on a further mosaic element) of a further mosaic element 100, together form the mosaic.

[0084] In some preferred embodiments, the number of mosaic elements 100 supplied with the kit, or used in the method, is preferably determined by reference to the overall size that the formed mosaic is intended to have. In some such embodiments, a length of the intended size of the formed mosaic is preferably at least substantially equal to a multiple of the longest distance spanning the first shape (not specifically referenced by reference numeral but is essentially enclosed by sides 400, 401 , 402 and 403), and a breath of the intended size of the formed mosaic is preferably at least substantially equal to a multiple of the widest distance spanning the first shape. In some embodiments the longest distance is substantially equal to the widest distance. In other embodiments, there is a difference between the longest distance and the widest distance.

[0085] In other embodiments, the number of mosaic elements 100 supplied with the kit, or used in the method, is preferably determined by the number of machines with which, or people, such as students, with whom, the kit or method is being used. The kit or method of some preferred embodiments is used for teaching purposes and or to allow students to learn from one another and or to allow students to learn from the exercise of causing an image to be applied to a front face 105 of the mosaic element 100 and or to allow students to learn from observing the image that ultimately spans the formed mosaic when all mosaic elements 100 are engaged in accordance with the invention.

[0086] Typically, the kit of preferred embodiments will not include, and the method of preferred embodiments will not use, less than two mosaic elements 100. Preferably, the mosaic will be formed by a plurality of mosaic elements 100, including the mosaic element 100, the second mosaic element 100, and a plurality of further mosaic elements 100.

[0087] In some preferred embodiments, interposed between the first shape and one or more of each projection is a frangible join. Preferably, breakage of a frangible join permits removal of a projection, with or without a sub-projection and or a sub-recess, which removed projection is engageable with a corresponding recess, correspondingly with or without a sub projection and or a sub-recess.

[0088] In some preferred embodiments, interposed between the first shape (not specifically referenced by reference numeral but is essentially enclosed by sides 400, 401, 402 and 403) and one or more of each projection 101 is a frangible join 106. Preferably, breakage of a frangible join 106 permits removal of a projection 101 , with or without a sub-projection 104 and or a sub-recess 103, which removed projection 107 is engageable with a corresponding recess 102, correspondingly with or without a sub-projection 103a and or a sub-recess 104a.

[0089] In a preferred embodiment of the invention wherein a projection 101 is separated by breakage of frangible join 106 from a side 400 of the mosaic element 100 or from a side of the second mosaic element, or from a side of a further mosaic element, that separated projection 107, with or without sub-projections 104 or sub-recesses 103, can be engaged with a recess 102, correspondingly with or without sub-projections 103a or sub-recesses 104a, where no other mosaic element 100 will be engaged.

[0090] As is shown in Fig 3, the separated projection 107 may be engaged with a recess on a side of a mosaic element 100 which side will form a side of an outer perimeter of a mosaic formed by the plurality of mosaic elements 100 so that the side of the outer perimeter at that point of engagement is flat rather than having a recess. In some such embodiments separation of the projection 101 occurs also at an outer perimeter of the mosaic formed by a plurality of mosaic elements 100, such that the outer perimeter at that point of separation is flat rather than having a projection 101. This is illustrated in figure 3 where the projection that has been removed (identified by reference numeral 107) is ready to be engaged with the recess adjacent to it. In this embodiment, the mosaic element 100, which has separated projection 107 removed from one side and engaged with a recess in an adjacent side will form a corner of the mosaic ultimately formed by the plurality of mosaic elements in accordance with the invention.

[00911 It will be appreciated by persons skilled in the art that numerous variations and/or modifications may be made to the invention as shown in the specific embodiments without departing from the spirit or scope of the invention as broadly described. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive.
