The Japanese edition of a coloring book of Altair Design, a kind of geometric pattern coloring that began in the United Kingdom. Each page is a grid of geometric shapes. You fill in the cells in any way you like, so each person ends up with a different picture.
The book is by five authors: Ensor Holiday, Roger Burrows, Roger Penrose, John Martineau and Haifa Khawaja. The Japanese translation is by Shigeto Watanabe.
There are 85 patterns to color. The book opens with a guide to the basic method. After the patterns, there are pages on the origins of Altair Design and how it developed later.
