Over the past seven years, Ben Willson has painted and estimated 10,000 pieces of chewing gum on the streets of London and elsewhere in Europe. Inspired by city living where there are oportunities to turn refuse into something completely new and interesting again, and the fact that there is nothing illegal about such an acitvity, Ben uses a blow torch to heat the gum, adds laquer then uses layers of acrylic enamel. He has become somewhat of a celebrity adding a bit of color and happiness to the grey streets of London, as told by news reports and short documentaries covering his work. You can see those at these palces: BBC & NYtimes. And a gallery of his work, here.
