Why do several elements of the foreground appear to be moving independently of the background in that animation? Notice on the right, the numbers 9, 12b, and 14 appear to move to the left, independent of the background. Definitely weird. I agree that strange things can happen, but I've never seen whole letters move up and down a page like this, nor foreground elements ever move across a "safety paper" background. Notice also the dot below the "S" in the David A. Sinclair picture. The last name in the signature moves in relation to the dot, but the first name/MI stay put. WHY?
