Chris Lasher, a grad student at the University of Virginia Virginia Tech (sorry, sorry), has posted some screencasts about version control based on the Software Carpentry notes at; a second series about using the shell should be up shortly. It's just plain cool to see the material picked up and carried forward in ways I wouldn't even have thought of a couple of years ago. Later: now there's, the Journal of Visual Experiments, and others --- the world moves on.
