On that recurring theme, someone on the LivingMath Forum posted a link to a talk by Ron Eglash on fractals in the design of African villages and other aspects of African cultures. Very interesting. I might have to go find some of his books. There is an article available online about the origins of binary code in African patterns, something he talks a bit about in the video.
He also has a website with tools to create designs using African fractals. And one specifically designed for kids as well as a set of tools specifically designed to relate to specific cultures. Hmmm. Lots of possibilities.
