50 Optical Illusions, 28 Jun 2011
A fun selection of cards to entertain. I look at five or ten every so often so that I can take in the detail. Some are quick and simple, others truly amaze. There is a special "revealer card" to help show how the design fools the eyes and just to convince you that what you think you see is not necessarily true. The reverse of each card explains the illusion in detail - even then you may not be convinced. A good buy at a reasonable price.
