BadAstronomer has posted an awesome video of the moon going through its phases for an entire year.
(it’s particularly awesome in full screen and HD.)
The video is based off a NASA webpage that will generate a picture of the moon for any hour, of any day, in the year of 2012 (and only if you’re in the northern hemisphere near the equator, but close enough). They have lots more videos and images.
Interestingly, the images are all computer generated — they’re not real photos. They are based on high-resolution images and topography data taken by the Lunar Reconnaissance Orbiter.
