From inside the dust jacket: "This first comprehensive guide to an intriguing new technique explains the language of Op art -- how we use illusions, patterns, progressions, black and white, and color to create art. It reviews the scientific background of visual perception, including psychological and physiological phenomena, and details the methods by which the artist and viewer participate in this experience."
