Publisher's Synopsis
An explanation of how to create optical illusions based on the idea of printing two overlapping images in red and blue and then viewing them through coloured spectacles. This book contains the material and instruction to enable the reader to create such a pair of glasses. It shows how different information has to be presented to each eye in a carefully controlled way and how to construct the correct perspective views. The ideas presented in the book include two-dimensional as well as three-dimensional illusions. There are also suggestions on how red and blue images can be used to produce original and amusing cards and informative graphic illustrations.
