Stereograms are 3D images hidden behind patterns.
Stereograms are 3D images hidden behind another image, usually a pattern or a texture. You can hide any image, shape, or text behind the pattern and, when you look at the strereogram after certain amount of time, the hidden image or shape starts to appear behind the pattern as a 3D image. All it takes to create a stereogram is a background image and an image or a shape to be used as a hidden image. Once you solve one stereogram, it takes only few seconds to see most of them.
