I can't believe i missed these guys at Confex - www.mindthecurb.com
Basically it's eco-friendly advertising - using either natural stuff like grass or snow, or by using anti-graffiti - cleaning off the image from the street rather than adding another level of grime. I think it looks ace - innovative, thought provoking, memorable but still sustainable.
