Stereogram

n. picture in which the delineated objects have an appearance of solidity; stereograph, photograph which appears three-dimensional when viewed through a stereoscope or special glasses

Stereogram may also refer to an integrated high fidelity system or music centre. A stereogram is an optical illusion of depth created from flat, two-dimensional image or images. Originally, stereogram referred to a pair of stereo images which could be viewed using stereoscope. Other types of stereograms include anaglyphs and autostereograms.Stereogram was discovered by Charles Wheatstone in 1838. He found an explanation of binocular vision which led him to construct a stereoscope based on a combination of prisms and mirrors to allow a person to see 3D images from two 2D pictures.
