Elvis lives. Tupac lives. And we have just discovered that M. C. Escher is also alive, well, living in Australia, and going by the name of Axel Peemoeller. Designer Peemoeller worked out the math to create, optically, directional signage that appears to hang in the air. Found in the carpark of the Eureka Tower in Melbourne, there's no technowizardy here, just a man with a can of paint and a few severely skewed letters. The result: mindbending. And bloody genius. Well done, Mr. Escher Peemoeller.
