To provide a new optical representation technique capable of changing an illuminating region, color and luminance with a simple operation, and projecting a background image and an artificial natural phenomenon, etc.
An optical representation device A and a scenario supplying device B are connected to each other via a USB cable C. The optical representation device A includes a light source 1, an image modulating device 2 modulating a light from the light source, a projecting portion 3 projecting the light modulated by the image modulating device 2, a drive means 4 driving the image modulating device 2 and a scenario playing means 5 which provides the driving means 4 with representation information and switches the representation information in time series. The scenario supplying device B supplies a scenario data file D, switching the representation information in time series, to the optical representation device A.
