ABSTRACT:
A light source focuses light on a revolving, apertured color disc. The portion of the light passing through the moving colored apertures is refracted by a projection lens into a small beam. The beam passes through the peripheral area of two large convex lenses sequentially positioned in the projection path. The optical properties of the two lenses combine to define distant focal surface. Each of the convex lenses has smooth optical irregularities randomly formed on each surface thereof for generating convolutions in the distant focal surface. The two lenses rotate slowly in opposite directions causing a smooth animation of the convolutions on the focal surface. The lens rotation continuously introduces new combinations of optical irregularities into the projection path each of which establishes unique and slowly changing convolution arrangements on the focal surface. The image is viewed on a reflective surface positioned proximate the distant focal surface. A multicolored light source may be employed in place of the colored disc. The colors may be modulated in response to a music input signal to provide a music coordinated color display.
