Astronomy Movies

Robert Knop of Vanderbilt University has some nice introductory astronomy movies that he has released under a Creative Commons licence. Amongst other things they show the celestial sphere, and the phases of the Moon although the one showing a month on the ecliptic made me feel a bit dizzy. He also has a nice Java applet which demonstrates why spiral arms are not material arms.
