So I've been impressed with IPython so far, it can be a little fiddly to install, but given the power I'm not going to complain. I'm now working on graphics and in trying to get up to speed going back and learning, or relearning, some basics. Today was B├ęzier curves, and thus this IPython notebook. Note that the content there isn't actually educational, you should follow the links provided to really learn about these constructs, I just wanted an excuse to try out LaTeX and plot some interesting graphs.
