Abstract
A fluid-filled, colored light pattern generator including a pair of transparent plates maintained in spaced relationship by a spacer ring. The ring includes an orifice for admitting fluid into a sealed cavity formed by the plates and the ring. Colored image producing members are suspended for random floatation in the fluid so that when a beam of light is passed through the plates, moving colored images are projected.
