which I discovered from Fromex.com absolutely amazes me.

Are squares A and B the same shade of grey?

Are you sure?

Yeah, I thought not, too. So I set about to prove that they are. Watch the progression below as I chop out the surrounding image which causes our eyes/brains to reach the wrong conclusion.

Neat, huh? And, no, I didn’t retouch the colors at all. They’re just as they started in the original image. (Clicking on any image will give you the full size image.)
