Penrose Triangle Animation

The Penrose triangle, first popularized back in the 50’s by mathematician Roger Penrose is a peculiar impossible object that resembles an illusion only from a certain perspective.

Check the animated #gif below and try and follow the ball moving around its path. It seems to make sense at first, but there’s just something off about it. Actually two corners follow normal Euclidean geometry, but that third one is connected in two different planes. As explained earlier – the literal Penrose triangle cannot exist in real life.
