I saw the below and thought it was pretty clever!

Clearly this ad for Wonderbra must be from the Brits or some country across the way, because the powers-that-be in America would never let an ad as good as this fly. Whether you're left- or right-brained, or whether you can see objects in those Magic Eye posters, it's almost impossible to miss this optical illusion (and it's a doozy of an illusion at that!).

Just keep your eye on the hypnotic spinner, and you'll see what we're talking about. We promise nothing will jump out and scare the bejesus out of you!
