Lying on London's famous Millennium Bridge, British artist Ben Wilson paints on a piece of dried gum. It has been crushed flat into the ground. The important thing is the gum is below the metal tread, said the 60-year-old Wilson. The beauty of it is they’re all different shapes and sizes..., he continued, describing pieces of gum. Wilson sees possibility in things most people avoid looking at. The flattened gum is a chance to turn a piece of waste into something beautiful. The artwork also is a way to surprise walkers and get them to take a closer look at the path they are on. By painting a picture which is so small, those that see it then discover a hidden world beneath their feet, Wilson said.
