Sobriety Test: If you take a look at the following picture , believe it or not, it is not animated.  Your eyes are making it move.  To test this, stare at one spot for a couple seconds and everything will stop moving.  Or look at the black center of each circle and it will stop moving.  But move your eyes to the next black center and the previous will move after you take your eyes away from it. Pointing your finger at each wheel will make it stop. The mind is a wonderful thing.(Loading may take a few moments)
