You often need to see deeper into things in order to understand it. This game of stereogram tetris shows this principle very well: http://eyeadventures.com/games/index.php

If you like stereogram images here are some more: 1, 2, 3, 4. And here are some really big ones (you can print it for the wall): 1, 2, 3, 4.

Have fun and look deeper into things.
