I'm working on a talk today. At one point it threatened to be interesting, but I think I've got that under control. Something that might spoil that plan though are some lunar animations from NASA. You can Dial-A-Moon at their website and download animations of lunar phases and libration.

Libration is interesting. It's the wobble in the moon as it gets pulled around in orbit. The downloadable animations bring this out nicely and NASA has gone to some lengths to make them as usable as possible for people. You can download the files in various formats from or watch them via YouTube.
