very fun book that shows you technique to make your eyes perform feats you never thought possible...you can see 3D pictures by looking at 2D photos...try it.
A fun, interactive book that explores the tricks our eyes and minds can play with our perception of reality.
Can you see the hidden pictures in here? You have to unfocus your eyes in just the right way . . . we had contests to see who could see each picture first. Warning - if you're one of those people who can't see stereograms, this is one VERY frustrating book. Not for small children - it is virutally impossible to explain to someone small how to do this.
