The French Ambassadors and the skull

The most awesomest thing I saw all week was this strikingly realistic painting by Hans Holbein the Younger. Besides all the symbolism presented by all the globes and time keeping pieces as well as the melancholic broken string of the lute, the best part about this painting is that THING on the floor stretched across between Jean de Dinteville (guy with the fur coat on left) and Georges de Selve (bishop to the right). It's an anamorphic image!!!

can you make out what it is? (hint: view from different angles & look at ::title::) Isn't it awesome?
