Folks at the NASA GSFC Scientific Visualization Studio created this amazing animation showing our view of the Moon over the entire year of 2012 with time resolution of one hour! The tipping, tilting, and rocking are due to the Moon's elliptical orbit coupled with its tilt. It is explained using captions in the video itself. Music is "Five Armies" by Kevin MacLeod, used under the Creative Commons license.
