London does have an awesome Graffiti scene! A lad who went to my University was a very talented street artist from London who now runs an outreach program encouraging street artisits from rough estates in London to understand how to market their street art to make a living from commissions and collaborative works with the mainstream. He once told me he knew banksy but I'm not sure if he was taking the piss out of me lol

These are some awesome pictures of street art Eric. Fantastic stuff!
