About Stereograms:

The 3D effect has been described in science journals for years, even as early as the mid-1800s, where the phenomenon was described as "The Wallpaper Effect". Optical researchers have been working with such images for decades, studying how the human eye works. They coined the term "Autostereograms". No special viewing tools are required to see autostereograms, unlike other three-dimensional illusion processes (which require special glasses or viewers).

The process works by repeating regular patterns of randomly placed objects (often called "pixels" after the pixels on a television screen). Through a sophisticated computer process, some of these pixels are then rearranged, creating a horizontal displacement. Because the pattern seems to repeat regularly, the brain erroneously interprets separate pixels in the same horizontal line as being part of the same spot on an object. Then each eye notices the different angle required to focus on that part of this imagery object and interpret the difference as an effect of depth.

(I am open to offers, and I have a wide variety of puzzles listed that are designed for children as young as 3, to very beautiful, intricate and difficult  puzzles for Adults. I also have games designed for children, learning games, cooperative games, as well as board games, strategy, trivia and Adult Party Games.
