Illustrations that Interact with their Physical Surroundings

The columbian illustrator Cesar de Valle's drawings are so detailed they could practically be photographs and if the illustratios weren't realistic enough
he then has them interact with the phisical world they find themselves in. A figure delicately balances on a pencil protruding from a wall or a girl balances on an actual string affixed to the canvas. I have a feeling his artwork would make an even greater impression seeing it firsthand, but regardless this is trullyremarkable stuff.
