This artwork is known as a reverspective, an optical illusion on a 3-dimensional surface where the parts of the picture which seem farthest away are actually physically the nearest. Patrick Hughes was the original creator of this type of art. The piece below was done by Brian Weavers and is currently on display at the Gallery at Ice in Windsor, UK.
