Abstract
Abstract The image projector as disclosed herein demonstrates an apparatus and method for creating a three-dimensional image. The projector is composed of a plurality of modules which are controllably illuminated to form the desired display. The modules are formed to be illuminated and to pass light from within through their walls and to prevent light from entering their outer walls when said modules are not illuminated.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
86 words
An image projector for displaying three-dimensional forms comprising: a plurality of three-dimensional modules, at least one of said modules aligned in each of the three-dimensional directions relative to the other of said modules, said modules being constructed of unidirectional light-transmitting material, illuminating means, said illuminating means being positioned within said modules, transmission means, said transmission means for directing energy to said illuminating means, and energy input means, said energy input means communicating with said transmission means whereby illuminating certain of said modules provides a three-dimensional form.
