Rotating Dots | ||||||
|
Follow the movement of the rotating pink dot and you will see just one color, pink. Now stare at the black "+" in the center and the moving dots turn to green. Now stare more at the black "+" in the center and soon all the pink dots will slowly disappear. You will only see a green dot which is rotating. Quite interesting, yes?
