The Cans Festival May 3, 2008

The graffiti impresario Banksy and a host of airbrush-wielding guerrilla artists blanketed the walls of a disused south London tunnel with offbeat murals as part of a three-day stencil-art street party.

The subversive British tagger turned art-house sensation marshaled more than three dozen international artists for what he is calling the "Cans Festival" - and is encouraging visitors to contribute their own graffiti starting Saturday.

"I'm hoping we can transform a dark forgotten filth pit into an oasis of beautiful art - in a dark forgotten filth pit," Banksy was quoted as saying in the Times of London, which carried a preview of the exhibition Friday.
