quick and dirty tonnetz on a torus for a friend's paper Since people keep asking, I've put the source code here: gist.github.com/854709 It's the only thing I've ever made in POV-Ray and is very simple. Source image is here: flic.kr/p/9nHkCi Someone made an animated version here commons.wikimedia.org/wiki/File:TonnetzTorus.gif with Matlab source code.
