This is an optical illusion that was created by an expert. And it is truly a unique one. To get a feel of this illusion, focus your attention on the central dot of the illustration then move the page slowly forward and backwards. The inner wheel seems to rotate slightly in a counter clockwise direction as the page moves towards you. It moves clockwise as the page moves away from you.

HOW  DOES  IT  WORK?

 Psychologists are stumped by this illusion. They do not quite understand why it happens. The explanation is similar to that proposed for the "Flexible Ovals" illusions, mentioned earlier. The brain is transmitted a series of images of the motion of the dot and wheel coming towards and moving away from you. The brain therefore tries to piece them together in what is a logical sequence of motion.
