Powers of Ten
A Simpson's parody (opening credits) of the Powers of Ten video.
There are a couple of versions of "the real one"—an older thing (with which there were problems in atoms and space both, I think, because it was old, from the 70's, and conceived in the 60's). The newer one is here, and starts in Venice:
and here's another, different one. The most fun thing about it is that it's in Catalan.
There more information and reference to some books about it here: http://chemeducator.org/bibs/0005003/530164gk.htm
