Remember those 3-D posters and books that were popular when we were kids? I could never see them...Well, my technique hasn't improved with age. Still can't see it. Darn.
But I hear it's awesome! The Half and Half have created a print that is as much fun as it's functional on your walls. Hey, and if you can't see it? Just pretend it's a Rothko and enjoy its calming effects...at least, that's how I make myself feel better for not being able to see it! :-p
