A stain by any other name

Bumped into this guy last night, painting over a gum stain beneath the tower clock in Crouch End. He's been doing this for some time and has quite a rep if you look here. Really nice idea, children particularly intrigued by his palette 'muffin'. Sadly I didn't have time to get his details, but if you follow the links in flickr, you'll see he's quite well known.
