Amazing Illusion

If your brain works normally this is neat 

This is the example of an amazing illusion!

The last sentence is so true!!

    

If your eyes follow the movement of the rotating pink dot, the dots will remain only one color, 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.

It's amazing how our brain works. 

Really there  is no green dot 

and 

the pink ones really don't disappear. 

This should be proof enough, we don't always see what we think we see?
