Rotating Illusion - Pink Eye Trick

[Zuiderelle]

Are you sure you really see it disappear?

If your eyes follow the movement of the rotating pink dot, the dots will remain only one colour - 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. There really is no green dot, and the pink ones really don't disappear. Proof enough that we don't always see what we think we see...

3. It's not the brain

It's using color theory to push the color receptors in the eye towards an different color. As your eye starts to burn in purple, it will push grey towards green.

Look half an inch to the left or right of the + after the purple disappears, and you'll get it

4. Take your science and shove it!

I say it makes my homunculi dizzy and cause them to mis-aim their colored laser beams on the projector in my mind!

8. The eye is sensitive to *changes* in light intensity

If it were possible to hold your eye completely steady, which it isn't, you'd find yourself unable to see within a few seconds. Your vision depends on your eyes always seeing a moving image. Your eye is always roving anyway, because the central spot where the resolution is highest (called the "fovea") is actually very small. Therefore you have to quickly rove your eye all over an object in order to see it.
