Stereogram

A plane image or pair of 2-D images which, when appropriately viewed using both eyes, produces an image which appears to bethree-dimensional. By taking a pair of photographs from slightly different angles and then allowing one eye to view eachimage, a stereogram is not difficult to produce.

Amazingly, it turns out that the 3-D effect can be produced by both eyes looking at a single image by defocusing the eyesat a certain distance. Such stereograms are called ``random-dot stereograms.''
