By observing the smaller animated #gif on your right, you may fall under the impression that all of the dots rotate together, simultaneously forming a spinning circle as they move along. But look what happens when we map their trajectories, and make their paths visible! As you can see, (as can be seen from the […]

Phenomenal optical illusion was just sent in by Melanie. Even though she can’t be sure about the author and its origin, Melanie noticed how the hole animated #gif seems to rotate (when observed as a whole), which is just the opposite from when you observe each and every individual dot by itself.
