Holy shit, this is the coolest thing EVER, courtesy of a great head-up story and photo essay from Nine MSN. 3D street artist Edgar Mueller has created "caves" on streets in Canada, Germany and now London, England, and his work, all done with acrylic wall paint, is pretty fan-fucking-tastic. For full appreciation, click the photos in the link and watch unfold it step-by-step. Amazing.
