Thanks for the improvements! I will merge, but it seems that in your updated notebook the animation example does not work. Any ideas why?

Thank you!

Sorry, I'm not sure - I assumed it was my browser and checked the .mp4 with VLC.

I added the explicit writer because of a traceback that referenced 'saving' which lead to a post stack overflow that suggested a bug in matplotlib which I haven't yet had a chance to track down.

Yes, there seems to be some problems with matplotlib and the animation module.. I've been having trouble to get something to work on the Mac with the latest version of matplotlib, but it works fine on Linux. So I'll merge your PR now, but will revert to the previous way of calling anim.save for now so that the video can be shown in the notebook.

Good call. Thanks again!
