In an area dominated by "two Prets, a Gap and a Starbucks" on every high street, Ben set out with the aim of stirring up debate with Westminster Council, who currently have a zero tolerance policy on graffiti and street art.
Ben's a man on a mission this year, having painted all round the world in all sorts of places with all sorts of people, but this is his first piece in the UK in 2011. So far this year he's had a show in White Walls Gallery, San Francisco, painted in Los Angeles Museum of Contempary Art, designed the 50th anniversary poster for Amnesty International and painted in a street art exhibition in Germany (streetart-wuppertal.com/).
The clip has been filmed by Abbie Brandon.
