Is it pink or green?
September 15, 2009Look at the following moving picture. If your eyes follow the movement of the rotating pink dot, you will only see pink. But if you stare at the back on the center, the moving dot becomes green.
Wait, there is more. If you concentrate for some time on the black at the center of the picture, all the pink dots will eventually disappear, leaving only a green dot rotating.
Aren’t optical illusions fun?
