Follow the Pink... um, Green.... huh?

I got this picture in an e-mail. It's an animated image, and the illusion is too cool to ignore.

Look at this. Follow the pulsation all the way around the circle of pink dots.



NOW, focus on the + in the middle. The moving dot turns green.

THEN, as you continue to concentrate on the +, the pink dots all disappear, leaving just the moving green dot.

Pretty freaky, eh? Especially considering that the pinks dots are the only things there. No green dots. And the pinks never disappear.

Keep that in mind, next time you're sure you saw something!!
