An amazing optical illusion. Really, you've gotta see this!

Beleive it or not, squares A and B are the same shade of grey.

Don't believe me? Here's proof (you may have to scroll to the right to see it)...

The explanation can be found here....

That was awesome! I love op art.

Okay, because the squares surrounding B are darker it looks lighter in comparison. And since A and B aren't near each other you have no way to compare them and they look like different shades of gray.
