The image above was inspired by the famous illusion "Rotating Snakes," created by Japanese psychologist and professor Akiyoshi Kitaoka in 2003.

Both are examples of a peripheral drift illusion, in which we perceive still images as moving ones. Interestingly enough, when you stare at one part of the photo without moving or blinking your eyes, that part stops "swirling" (while the circles in your peripheral vision continue to "move").
