Walter Wick’s Optical Tricks, ISBN 0439139562
Five out of five stars
This is a wonderful book for children of all ages, for it forces the viewer to look closely and understand how an image can deceive you. Each of the images appears to have a certain form, yet when examined closely or from a different perspective, it becomes clear that the structure is quite different.
I strongly recommend this book as a fun way to challenge youngsters and improve their observational skills. Optical illusions are some of the most entertaining things that are also educational.
