I've just seen this on Lance Armstrong's twitter feed. A really astounding installation. I especially love the train. I think all train operators could do something similar to liven up normally boring looking carriages.
I also heart the duel purpose in that the canvases are waterproof so provide shelter and not just a pretty picture. With the likes of Google Earth emerging, I could see this art application taken to giant scales.
