We don’t always see what we think we see. If your eyes follow the movement of the rotating pink dot, you will only see one color, pink. If you stare at the black plus sign in the center, the moving dot turns to green. Now, concentrate on the black plus sign in the center of the picture. After a short period of time, all the pink dots will slowly disappear, and you will only see a green dot rotating! (There really is no green dot, and the pink ones really don’t disappear.)

Wow, that is amazing!
*does it again, giggling*
Have seen that many times.. It's not WYSIWYG ....
Yes its a nice illusion, but the pink dots
do disappear (and then reappear). It is the disappearance of these pink dots which tricks our brains into seeing a green dot. If you view this out of the corner of your eye (by turning you head away from the screen) you can still see the pink dots disappearing, so it is a gif animation. Illusions such as these do not work unless you are looking directly at them.
Still, the green dot is an illusion, I'm not doubting that. I'm also not doubting the fact that after a while all the dots disappear, I can see that happening.
The explanation behind the image can be seen here:
http://illusionsetc.blogspot.com/2005/07...usion.html and apparently a lot of people have become confused over what is real and what is not in this illusion.
I also found
this which allows you to change the speed / colour of the dots...pretty cool!
i don't like such illusions but it is O.K.
