Abstract
A system of three-dimensional projection comprising in combination a screen and a viewer, said viewer embodying a mask containing see-through slits, means for projecting at least two different perspectives on the screen and means for effecting movement of the viewer to traverse the mask from left to right and from right to left such that from a given vantage point, each of the beholder's eyes sees a different perspective view, each of which is formed by the scanning motion of the screen at a rate such as to provide the illusion of an image continuous in both time and space.
