It was over my head :) I don't have a typical CS or Math background and reading one of the solutions blew my mind (http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/116106). I don't really know what spherical interpolation vs. linear interpolation are. So it was interesting, but I didn't really know where to start.
