I have collaborated with the mathematical artist Edmund Harriss on two mathematical colouring books. These books are galleries of images from a wide spectrum of mathematical ideas. Each images comes with an explanation of the ideas behind it.

More than 50 images from fields including tessellations, reflections, modular forms, topology, fractals. Lie groups, frieze patterns, the travelling salesman problem, reaction-diffusion, and much more.

More than 50 images from fields including Voronoi diagrams, transformations, knots, polyhedra, Lissajous figures, the golden ration, space-filling curves, cellular automata and much more.

This book was originally called Snowflake, Seashell, Star.
