ABSTRACT:
A light computer is provided for illuminated and animated displays. Light planes are illuminated and images carried thereon are lit when light is applied to any edge. A moving light and opaque coatings on the edges of the light plane are used to vary the sequence and time the frequency and duration of the lighting of the plane. When an opaque coating is positioned between the light and the plane, the plane does not light. Only when the opaque coating is not present and the light is present is the plane lit. In a preferred embodiment, the light source is mounted at the end of a stack of circular light planes and light from the light source is admitted to the edges of the light planes by means of a rotating mask having a window leading to a prism for reflecting the light onto the edges.
