Can you believe your eyes? - Harold E Yuker etc al.

Over 250 illusions and other visual oddities Can You Believe Your Eyes? contains over 250 illusions and visual oddities from all over the world, many never previously published in a book, others created especially for this collection. It requires more participation than just reading; to really appreciate it you will have to do a great many things with it that you do not with other books. For example, in chapter 17, you will be constantly turning it upside down and then right side up to see what is there. There are several chapters where you will have to use a ruler to convince yourself that what you see is really not true. In chapter 6 you must stare at the illusion for 30 seconds and then shift your gaze to a blank sheet of paper, or wall, to see the effect. Sometimes you will have to cross your eyes, bring the book up to your nose, hold it away from you, even wiggle it slightly - the variations are endless! Each illusion is accompanied by explanatory text that throws light on its dynamics, so that the reader will be educated as well as entertained. From bilingual ambigrams to Sander's parallelogram, from the Traffic Illusion to the Necker Cube, all the bizarre and wonderful oddities presented here will have the whole family craning their necks for hours of fun!
