Coca-Cola Bottle by julian beever

The "Pavement Picasso," English chalk-artist Julian Beever, crouches next to one of his most-famous creations, "Coca-Cola Bottle: Is It the Real Thing?" To create his tromp l'oeil drawings, Beever uses distorted perspectives to make images seemingly 3-D, a technique called anamorphosis. "The secret is to set up a camera on a tripod and keep it in one spot and check every mark you make," said Beever. "It's really just playing with perspective to make it appear different to what it really is." (Julian Beever)
