Cool project from the DDB China Group for the China Environmental Protection Foundation:
We decided to leverage a busy pedestrian crossing; a place where both pedestrians and drivers meet. We lay a giant canvas of 12.6 meters long by 7 meters wide on the ground, covering the pedestrian crossing with a large leafless tree. Placed on either side of the road beneath the traffic lights, were sponge cushions soaked in green environmentally friendly washable and quick dry paint. As pedestrians walked towards the crossing, they would step onto the green sponge and as they walked, the soles of their feet would make foot imprints onto the tree on the ground. Each green footprint added to the canvas like leaves growing on a bare tree, which made people feel that by walking they could create a greener environment.
