An idea worth spreading

Here's a video of a lecture by Ron Eglash about fractals in Africa. its quite interesting in terms of the small bit of history of fractals you get as well as in terms of those he discovers in African settlements and art. I don't know if its true that fractals are not just as present outside of Africa but this is cool. I thank Chris Millington for sending this.
The video is part of the TED series - I posted one before. Its just shy of 17 minutes long.
