What colour is the rotating dot? If your eyes follow the movement of the rotating pink dot, you will
only see one color, pink. Now, concentrate on the black cross in the
center of the picture. After a short period of time, you’ll notice that the rotating dot changes colour to green! Wierd huh?
Thanks to Toni for the pic
