This awesome animation by the visualization folks at NASA’s Goddard Space Flight Center shows the phases and position of the Moon throughout 2011 – a full year of the Moon compressed into 2.5 minutes!
What’s really interesting is how you can see the wobble of the Moon in its orbit. Even though it always faces the same side toward Earth, there is a bit of variation in how it is positioned, so a bit more or less of the regions along the limb angle into view over the course of a year.
And just in case you were wondering, yes, the Moon does rotate. It rotates at the same rate as it orbits Earth, so as to remain tidally locked with our planet. This is a common feature of many moons in our solar system.
