This text contains close to 100 optical illusions, from picture puzzles with hidden objects, to shadow puppets, solid objects that cannot exist, straight lines that wave and bend, and pulsating patterns.
The book is sort of a mishmash but that is not a bad thing. It is really pretty fun. It covers optical illusions as well as those of hearing, smell, touch and taste. It also includes various puzzles and activities. All of the illusions and tricks are explained, in language which never gets technical but always manages to clarify what's going on.
