apod, the Astronomical Picture of the Day, often has absolutely stunning images. Today it's an animated gif of the moon over a month (or rather a lunation, a lunar cycle). I've put it in cuts, since it's 400+K, but it's well worth looking at even if you have a slow connection.

Amazing! I've known about libration for years, but it wasn't until I saw this that I got a feel for how significant it is. The change in angular diameter is also more that you might think.
