Ron Eglash (who was mentioned before on the forum) is an ethno-mathematician gives a roughly 17 minute talk on his work on African fractals. He covers building and organization, art and a few other topics briefly and describes how complex these scalable organizational structures are. There is a brief section on questions he was probably asked frequently since he originally did this project.
