Formerly at the California Institute of Technology, Al Seckel is a leading authority on visual and other types of sensory illusions. He is the author of 15 books on this subject, including the classic The Great Book of Optical Illusions. He is also well-known for his illusion column in National Geographic Kids magazine.
I used this for a summer camp and the kids and adults all loved the comprehensive guide to optical illusions. The picture qualities are very high and the illusions are terrific.Published 5 months ago by Michelle Gray

The subject of the book is how clever pictures and clever artists can fool your brain. You will enjoy it.Published 12 months ago by Margaret Dunne
