Visual illusion

I receive a lot of emails about visual illusions and see them on many blogs, but I’ve never seen a stronger illusion than this one. This is one of my favorites, a great 3 in 1 visual illusion. Consider the animation below:

Step 1:

  • If you follow the pink dots, they will appear pink to you.

Step 2:

  • If, however, you look at ‘+‘ in center, the moving dots appear to be green.

Step 3:

  • (Tough one) Concentrate on the plus sign (+) in the center for a while, the dots will disappear slowly!
