This is a sweet project, but what's really awesome is how clearly he explains the whole thing, from hardware to software. I'm also really impressed at the way that he uses the tablet to quickly and interactively generate diagrams in (mostly) real time while speaking. Sure, he could make a "cleaner" animation but doing it this way is just as effective and probably saves a ton of time.
