Jody Xiong from DDB China created a very impressive outside installation on the the pedestrian crossings in China in order to demonstrate how choosing walking over driving actually helps the environment. They put massive white canvases with drawings of bare trees on the pedestrian crossings in 15 different cities of China. On both sides of the sidewalk they left huge sponge cushions soaked in green environmentally-friendly paint. Every time a person crossed the street, the paint got on his/her shoes turning their footsteps into leaves.
