ABSTRACT:
A display device which imparts to the observer an illusion of depth. The device includes a partially silvered front mirror, illuminating means disposed behind this front mirror, and a fully silvered rear mirror positioned behind the illuminating means such that its reflective surface is parallel to and facing the partially silvered front mirror. The illusion of depth results from the successive reflections of the light from the illuminating means between the two mirrors, establishing a series of virtual images which appear to extend back into the device.
