Blatantly ripped from Kottke: the film Powers of 10 is online. You'll probably have seen it before, or one of the rip-off imitations (few of which are as good as the Simpsons version). What I never knew is that it's by Charles and Ray Eames, who are perhaps better known for... er... designing chairs.
I think I'm going to have to go and read about them, now.
