Speedy Graphito

Im not sure what I think of Speed Graphito's art as a whole, but I definitely like his Mona Lisa made of spray cans. The reason I think it appeals to me is not because the finished product is beautiful, but because the process was beautiful. Each one of those spray cans was used to make a previous art, and although one could consider them useless, he brings them together to produce a final art form. The coolest part it that he had to use each and every spray can or they wouldn't have the color stained on all their tops. I've seen another pixelated Mona Lisa recently but I can remember where.
