That artist was featured in a British newspaper a couple of times and I ended up tearing out the pictures of his artwork and keeping them because I couldn't bear to screw them up and throw them away lol.
I think he is so talented and the pictures are fascinating to say the least! I just couldn't stop looking at them.
Brilliant link, some of those piccies I have never seen, I think I will stick it in my favourites!
One other thought, I think he does the drawings in chalk (could be wrong), it seems such a shame, if that is the case that the rain could just wash them away

.
I think he should be employed to do 3D art on some ugly walls, even those obsessed with grafitti surely wouldn't ruin those!
