Via Travis Hallenbeck, African textiles using a programming language called Logo, specifically the GS LogoWriter on an Apple IIGS computer. The page linked to, a text written 12 years ago, goes into great technical detail as to how the patterns were created. I was not previously familiar with Logo or even that generation of Apples; it looks like another language-cum-family of gear (like Amiga, NES, etc) with a philosophy and a cult behind it. Obviously I'm spewing hot air here, being more interested in the beautiful finished product than how anyone arrived at it. But see What is Logo? if you're as un-up-to-speed as I am and want to know more.
