You may have seen drawings of impossible objects, but have you ever seen them photographed? Wick's book of optical illusions leaves readers of all ages wondering just how the I Spy photographer does it! This book combines fascinating optical illusions with simple explanations of how the visual tricks work. Photos of "Stairs to Nowhere," "The Phantom of the Forest," and more seemingly improbable images are a delightful treat for the eye and mind. Beautiful, challenging, and just really fun, this book has to be seen to be believed. And once you see it, you won't be able to put it down!
