Books marching around a bookcase: stop-motion animation

CrazedAdMan's stop-motion animation "Organizing the Bookcase" depicts books organizing themselves by color on a bookcase, then marching around and doing synchronized maneuvers. It's great fun and puts me in mind of the time when my old roommate got a new girlfriend who reorganized all our bookshelves by size. My, that was a day.
