Fantastic Beasts and Where to Find Them

In this movie there is a clock with circles spinning around the clock face. I found Link redacted –Deacon Vorbis (carbon • videos) this video where the clock is shown at 0:42. There must be mathematical formulas for where any given point on those circles is inside the larger circle.— Vchimpanzee • talk • contributions • 22:54, 14 February 2019 (UTC)

If you look very closely, you will see that the three circles on the clock face are attached to one another. So, they behave no different than the hands of the clock. By having them go around much faster than the second hand, it gives an illusion that they are three circles moving independently. If they moved slower, your eye would easily track the movement and you'd see it is as three circles all attached to one another as one big fat hand of the clock. 209.149.113.5 (talk) 14:08, 15 February 2019 (UTC)
