Abstract
An apparatus for generating and projecting a bright, narrow, color selectable beam of light has a light source for producing a beam of light directed into a collimating lens and from the collimating lens into a prism. The prism disperses the light into a plurality of color components which are directed into a movable focusing lens for focusing the dispersed light into one of a plurality of positions onto an aperture to thereby select one or more color components of light through the aperture responsive to the positioning of the focusing lens. The focusing lens is moved responsive to an electric motor, which moves responsive to a voltage signal. The selected color component may be further collimated and directed against a series of movable mirrors for generating a variety of scanned patterns of colored light onto a flat surface. The moving spot of light will appear as patterns due to the persistence of the eye which blends the fast moving spot into long continuous lines.
