Cameron has quite a few other experiments which are worth the look. Some are useful, some are fun, and some are both. For example check out his Mouseboard, widgEditor, Circtangles, and Technicolor.
It is also great to see that Cameron has embraced the whole open source approach. The widgEditor code for example is released under a GNU General Public License. Cameron, you're a living legend (and I was not paid to say that).
Thanks also to Chris for putting me onto BokehType.
