How Normal is your Brain

If your brain works normally this is neat. This is another example of an amazing illusion!!!
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 see only a single 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.

    Nice... The spots really disappeared after I stared a long time. But I only had a glimpse of the green dots. And when I tried to stare longer, that's when all the dots disappeared. Does this mean that my brain isn't normal?
    And oh, one dot is lacking at the upper right of the illustration. Is that really how it was, or is it just me? ^__^

    Swirlz, your brain is normal. You need a normal brain to see what you have described.
