Albert Einstein is watching You!

This noble glass block is much more than just a paperweight or a tasteful decoration. The laser-engraved face mask of the famous physicist is a perfect demonstration of the so-called depth reversal, one of the strongest optical illusions that hardly anyone can escape. If one looks from the back into the negative form of the face and moves, one gets the impression that the eyes are following the viewer. You have to see to believe it!
