Autostereogram meaning
A single-image stereogram, designed to trick human eyes and brains into seeing a three-dimensional scene in a two-dimensional image.
To help see a random dot autostereogram correctly, pull the eyes (face) towards, say, within one inch of the random dot autostereogram, and then slowly pull away, until the central 3D shape coalesces into view.
