Here is an unusual illusion. Firstly, keep your mouse away from the image and let it just rotate. Get as close as you can and watch it rotating for about thirty seconds. Then without taking your eyes off of it move your mouse over the image. Then just enjoy!. It also works if you look at anything else, try looking at the back of your hand.
