African Fractals: Modern Computing and Indigenous Design

Thanks for the reply. Updated the OP - my areas of interest are the kinds of things that get posted about on HN, but I'd really like to broaden my horizons and learn about things like politics and economics and philosophy, anything interesting really. I'm leaving tomorrow so the only requirement is that I need to be able to get it before then. I had planned on downloading/buying stuff for this during the weeks before I leave but just never got round to it. African Fractals looks interesting though, I'll check it out. Thanks

Areas of interest? Free or paid? Edit: book suggestion: "African Fractals", by Ron Eglash, http://www.amazon.com/African-Fractals-Modern-Computing-Indi... (http://www.amazon.com/African-Fractals-Modern-Computing-Indigenous/dp/0813526140) "..traditional African settlements tend to use fractal structures-circles of circles of circular dwellings, rectangular walls enclosing ever-smaller rectangles, and streets in which broad avenues branch down to tiny footpaths with striking geometric repetition. These indigenous fractals are not limited to architecture; their recursive patterns echo throughout many disparate African designs and knowledge systems."
