Optical Illusion!

[Fly2e]

[center][color=#0000ff][size=12] Remember, your brain has to work NORMALLY to see this.
If your brain works normally this is interesting.
This is another 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.

That's awesome! I didn't expect the pink dots to disappear but when they did I was like, WOAH!

That's nothing compared to this...! Try it - it's freaky!

Its called a negative afterimage.

http://en.wikipedia.org/wiki/Afterimage

Red-green cones are paired together in the foveal region of your retina (also present are blue-yellow, and in the peripheral part of the retina there are black-white rods), when red turns on, green turns off because these are opponent colors (one is negative of the other).

[The Ruptured Duck]

Correction:  your rods do not detect black-white.  Instead they only detect light, and when there is less  or no light, they do not turn on.
