If you take a look at the following .jpg, let me tell you ... it is not animated. Your eyes are making it move. To test this, stare at one spot for a couple seconds and everything will stop moving. Or look at the black center of each circle and it will stop moving. But move your eyes to the next black center and the previous will move after you take your eyes away from it.... Weird

Pretty kewl

Yeah...that's pretty neat.

Wow, that's awesome!

I was able to get it to stop moving...But to do that, I had to stare at them all at once........NEVER TRY TO STARE AT MULTIPLE THINGS AT ONCE!!!!!!!!!!!! YOU'LL MAKE IT STOP MOVING, BUT YOU'LL GET A REALLY BIG HEADACHE!!!!!!!!!!!

ive seen before. it looks real

if you stare at all the dots at once they seem to blink

I can get the inner 8 to stop moving all at once without any strain. Pretty cool illusion! :goodjob:

awesome illusion. seen it before. hard to stop.

My head... :crazyeye:

Heh, brains are so dumb.

Optical tricks, hehe. Not very funny, but worth a look. I wonder who comes up with such things? Somebody must have found out how this works.

Good stuff, but I personally prefer magic eye images.

It makes me frustrated....

If you concentrate hard enough on one black dot, the others stop moving :)
Optical illusions are fun, but somehow frustrating ;)

If you don't move your eyes at all, the whole picture will stop moving. :)

Pretty neat. :D

Holy crap...I could feel my brain pulse while looking at that.
