The Little Giant Book of Optical Illusions
by By Kay, Keith
Category: Games , Trivia

Bats and birds that look like faces. Skulls that pop up on anything white. Three donkeys with three ears be-tween them. And walls that disappear. Relax, they’re only optical illusions. Examine thousand-year-old drawings, find out about closure, perspective, and “the Rubin vase”, and how these tools can untangle the tricks found in this volume.
