Julian Beever is an English artist who’s famous for his art on the pavements of England, France, Germany, USA, Australia and Belgium. Its peculiarity? Beever gives his drawings an anamorphous character, his images are drawn in a distorted manner which gives them a 3D appearance when viewing at the correct angle. See for yourself -- it’s amazing !!!
