that is really cool - and is a good example of our brain altering what we see to try and make sense of what is happening.

Wow... ...how can that page know when I stare at the black cross so it can remove the pink circles...

I have always had a fascination with various optical illusions. I even tried to do a science fair project on them invloving "pervieved motion" images and giant toads(Bufo Marinus). they only will eat moving prey, so I figured I would see if toads percieved the illusions the same way humans did... They didn't or my experiment was jacked up...

Fish: sorry to here it ,

I have alway liked the unconstructable objects:

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

Paradox illusions offer objects that are paradoxical or impossible, such as the Penrose triangle or impossible staircases seen, for example, in the work of M. C. Escher. The triangle is an illusion dependent on a cognitive misunderstanding that adjacent edges must join. They occur as a byproduct of perceptual learning.

hmmm... I wonder where the green color comes from.... well, our minds obviously... but why? Is it just our brains trying to get used to the grey background color when there is a sudden absence of pink? But then again... why would the pink go away aftera while? AHH!! so weird. I love it.
