Christoffel Pattern Coloring Book

There are 50 unique patterns in this book, each on its own physical page.
The authors have for many years been obsessed with finding patterns in nature and in mathematics. This is just a very small sample of some of the interesting patterns they have discovered.
The patterns are named after the German mathematician Elwin Bruno Christoffel (1829-1900). He did not directly produce them, but they are related to some of his work.
Details on how the patterns are created can be found in the book Pattern Generation for Computational Art.
