Cool illusion

Ok, this is a brain trick I received from my sister via e-mail.

********************************************

If your eyes follow the movement of the rotating pink dot, you will only see 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 a green dot rotating.

It's amazing how our brain works. There really 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.

***********************************************

In other words, the saying "I've seen it with my own eyes" has just lost it's credibility. Who else do you trust then? *ponders*

there are green dots and the pink really disappear.

TO proof that, just cover up the whole thing with your hand and leave 1 dot visible. U will constantly see the pink dot changed to green dot.

Try it urself....

yeah man, i know. It's really something, that's why it's up. Heh, that's why it might take humans a long time to create computers that can do a fraction of what the brain can do.

Rate it!
