There are countless optical illusions but I think this is one of the best.

The squares A and B are exactly the same shade of grey.

(I did actually have to copy and paste the image into Paint and use the colour picker in order to draw a line through the two squares just to prove it to myself)

Interesting that the illusion can be reproduced by laser etching.
