Amazing Optical Illusions

For centuries, our ancestors liked to while away their spare time by
inventing and sharing optical illusions. This book proves that nothing
has changed since those days. This collection of more than two dozen
optical illusions, some of them hundreds of years old, will challenge
and delight people young and old. There are elephants whose feet do not
seem to match their legs. There are faces that look happy when right
side up and unhappy when upside down. There are rectangles that make you
see spots and circles, and the spots and circles make you see spirals.
The illustrations are crisp and colourful, making the illusions all the
more enjoyable.

The one minor drawback of the book is that most of the illusions are
already well known. Still, if you know someone who hasn’t seen the two
faces/goblet optical illusion or the 16th-century Emperor Rudolf II of
Italy portrait made of fruit, this is a fine introduction. Recommended.
