Recently, I received a book "Illusion - Confusion" by Paul Baars, in which he collected examples of almost all known kinds of illusions. There's a lagre section about impossible figures in the book. Among other images, there's one my impossible figure published there.
The distinctive feature of the book is using double page spread for representing large images. For example, Escher's Metamorphoses II fit into two fragments, when in meny other book it was divided into much more parts.
The book will be a good supplement for collectioners and astonishing gift for everyone.
