Or, why you shouldn't necessarily believe everything you see.
If your eyes follow the movement of the rotating pink dot, you will only see one color, pink. But if you stare at the black + in the center, the moving dot becomes green. Now, concentrate longer on the black + in the center of the picture. After a short period of time, all the pink dots will slowly fade away and you will only see a rotating green dot. Don't see it? Well, keep staring! (But be careful; if you are like me, you will start to feel nauseous after a short time).
It's amazing how our brain interprets this animation because there really is no green dot, and the pink dots don't disappear. This nicely illustrates how we don't always see what we think we see.
