From Stereograms to Autostereograms

The stereopsis’ scientific notion inspired the neuroscientist Béla Julesz to create the first random-dot stereograms, which were simple black-and-white pictures. Julesz’s stereograms were uncomplicated but revolutionary and were the basis for the invention of the autostereogram.

The autostereogram is actually computer-generated and was initially produced by Christopher Tyler, a former student of Julesz. Autostereograms like the one you see above (containing a “secret” heart) are, essentially, un-marketed Magic Eye pictures! The practical science behind these images is so fun and quirky it was only a matter of time before they started to be branded as an entertainment product.
