In a bare, undecorated studio, a young woman (Bettie de Jong) in a cloth leotard enacts a simple series of dance movements, starting and ending in a reclining position on the wood floor, and in between gracefully flowing through an elegant, slow-motion set of pirouettes and fluid turns. She repeats this dance nine times, and each time Harris varies his filming methods to capture her movements in subtly different ways. —http://seul-le-cinema.blogspot.com

At first I focused on following her movements because I was reminded of a ballerina music box, but that was a mistake. Then I made the music a conductor of what my eyes were seeing, but that was also a mistake. Then I began to follow the camera's lead and realized that this is filming at its most immaculate. This is what the eyes could have never seen otherwise.
