How a differential gear works -- a-ha generating video
I posted this in March 2011, but as Kottke says, "it's so good, here it is again." "How a differential gear works" is a short industrial film that does a better job of explaining how differentials work than any other materials I've seen -- a real "a-ha" generator.
