I stumbled upon this lately. This is an optical illusion of motion that will require your dynamic participation. Just look at the dot at the center and move your head forward and backward like what a chicken does and see the two rings rotate in opposite directions. Of course, the rings aren't really rotating. Your brain just laets you think they are. What's really moving is your head. Show it to others in the room and you'll have a blast watching them act like chickens in front of your monitor!
