I saw your comment and was like: "wait a minute... surely its not the same guy as the mechanical watch thing, is it?!?!?!"

Absolutely blown away. As someone with a "design for learning" degree which I've found to be rather useless, I'd gladly have traded by dozens of thousands of dollars for a chance to learn with this guy. The technical sophistication combined with the incredibly didactic and clear flow of his work is truly insane.
