I’ve added several designs to my Zazzle store. They’re based on the concept hinted at in my last post.

Everyone needs coffee cups, right?

Do any of these 27 designs inspire you to buy a coffee cup?

This image, which I made a few years ago, is based on a tiling of the hyperbolic plane with triangles whose angles are π/2, π/3, π/7. Other than the 7, which can be changed to any higher integer, I couldn’t vary these numbers without ruining the effect. Recently I thought of a simpler, and thus more general, way to generate the ribbons.

My strip representation of the hyperbolic plane inspired Vladimir Bulatov to explore weirder conformal mappings thereof. (Conformal means angles are preserved.)

A space-filling path through this square is matched to an analogous path through the color-cube.

I had this idea in mind for years but the algorithm for Hilbert’s curve defeated me; then I stumbled on Steve Witham’s Python code, and whipped up this doodle in half an hour.
