Donald Regalmuto has put together an edit of my presentation in Marin County in October 2010. (It even includes my first ever attempt at animation, done with the open source program Synfig Studio. Even though it's extremely basic and lasts only about 15 seconds, I'm really happy to have animated something.) The video is about 18 minutes and may be of interest and/or use. This was put together thanks to Lori Grace.
