Watch Principles of Harmonic Motion (1991) : Full Movie Online Free "While not addressing the issue in a very overt manner, this piece has something to do with the thrilling and 'awful' process of actively engaging in perception and how we oscillate between forgetting and remembering that activeness as we age. In 'Principles of Harmonic Motion', I take a painterly approach to the image and rely on a subtle but carefully composed stereo soundtrack to amplify the sense of physical and psychological space. The images, sounds and structure are sometimes somewhat abstract while preserving a strong grounding in representation." –Leighton Pierce
