Omg My Eyessss
 

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

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 of time, all the pink dots will slowly disappear, and you will only see a green dot rotating.

Neat!

stop fucking with the rods and cones in my eyeballs!

Thats nothing..

that makes my eyeballs hurt.

I'll give ya something that'll hurt your eyes...

..good thing he didn't finish that sentence. =P

hahaha ew

I was referring to pepper spray

Don't lie, you were talking about man spray.:D

Ahhh true story

You have a pretty good idea of what is going to happen in this illusion, but it is pretty cool, regardless. Stare at the center of the flag for at least 20 second - even longer to enhance the effect - and then look at the white area of your computer screen, a light colored wall, or a white peice of paper.

Now try this - try it again, but this time don't stare at the center. Move your eyes over to the right or left. Then, when you are looking at the after image of the flag, as your eyes try to focus on it, you'll see that they can't, and the flag will continue to slide around in your vision. As you may have guessed, this is because the image is burned into a certain place on your eye, and as you naturally will try to focus on the center and get it to stop moving, it will move around even more.
