Pink dot illusion
If your eyes follow the movement of the rotating pink dot, you will only see one color, pink.
If you stare at the black + in the center, the moving dot will turn to green.
Now, concentrate on the black + in the center of the picture. After a short period of time, all the pink dots will slowly disappear and you will see only a green dot rotating.
There really is no green dot and the pink ones really don't disappear.
A tip o' the hat to Lou.
A little googling found this page, which seems to be the source of this illusion. It's a recent addition to Michael Bach's collection of illusions.
