Can you get this one ?

Today, I was surfing across just to find something crazy, something stimulating. My search ended with the following illusion pic - one of the best I have ever seen.



Now the concept is: Both the A and B blocks are same shades of Grey. Period !!! Spend sometime here to really have a look before I lead to resolve the mystery. I know you will need my help :)

Done ? Perhaps you can read the explanation here. Could you make it ?

Perhaps try desi estyle. Copy this image in your mspaint, cut a piece from each block and compare. The explanation above will start make sense :). One of craziest things I have seen. How about you ?
