The Golden Ratio Coloring Book: And Mathematical Patterns

Ninety-six pages of spirals, polyhedra, tessellations and Fibonacci sequences, all drawn from the golden ratio and the other patterns that mathematics keeps finding in shells, sunflowers, galaxies and cathedrals. Steve Richards's line work is intricate enough to hold your attention for a whole evening and open enough to color with pencil or a fine marker.

A very good present for the friend who is equally happy holding a compass or a paintbrush, and one of the few coloring books we would leave out on the coffee table.
