Sketchcasting - Next-generation screencasting for code

Thanks to a flash grant from the Shuttleworth Foundation (via Philipp Schmidt of P2PU fame), I was able to take a few weeks off between my time at Grockit and the Minerva Project to build something brand new: sketchcasting. What I built — inspired by an experience I had running a P2PU course using Sketchpad in 2010, and enabled by the great Mozilla Popcorn project — functions a lot like the new interactive code-casts on Khan Academy. Watch the code being typed as you listen to an accompanying audio narration, pause playback to fork and experiment yourself with the code at any moment, then show and share what you create (an example). The best part is that anyone can record a sketchcast, not just me.
