Move over, hopscotch boards. U.K. artist Julian Beever and German artist Edgar Mueller are two dudes who independently make some pretty amazing 3D chalk sidewalk murals. It's almost as if the guy from Mary Poppins and Wile E. Coyote started giving art lessons. These optical illusions use perspective so that when seen from the right angle, the drawings seem as real as a photograph. Curious? See how it's done.
