Rotating Illusion - Pink Eye Trick
Are you sure you really see it disappear?

If your eyes follow the movement of the rotating pink dot, the dots will remain only one colour - pink.
However if you stare at the black “+” in the center, the moving dot turns to green.

Now, concentrate on the black “+” in the center of the picture.
After a short period, all the pink dots will slowly disappear, and you will only see only a single green dot rotating.

The two concentric arrays of "candies" appear to rotate in the different directions when we approach or move away from the figure while fixating at the center. Interesting tricks the eyes play.
