Abstract
A method and apparatus for projecting multiple patches of full spectrum, rainbow colors to multiple, widely distributed locations is provided. The invention enables the display of such patches on a surface area toward which a source of light is directed, for example the walls and ceiling of a room from sunlight entering the room through a window in the room. The method and apparatus provide first for the refraction of the light from the source of light, and secondly for both the refraction and the reflection of the initially refracted light. The initially refracted light is projected onto a surface of the room as main multiple spectral patches; and the refracted-refracted light, and the reflected-refracted light are projected onto other surfaces of the room laterally of the main patches as additional spectral patches, creating in all, multiple spectral displays of full spectrum, rainbow colors nearly surrounding a viewer and changing in position and shapes with the movement of the sun or other light source.
