Here are some answers to questions people keep asking me: - the ringing ball comes out of the red flipping box. - the painting tilts, which causes the top ball to run down it. - a keen eye will notice the egg unravels out of its foil wrapping. - at around 1:52, the balls are rolling behind a sheet of glass that is at a slight angle so that the balls have to revolve a lot just to move a small amount. - it took about 6 months to make and 3 days / 200 takes to film.
Much credit must be give to the amazing Pitagora Suicchi ones for all their original ideas!
