The China Environmental Protection Foundation with DDB China, launched a campaign called Green Pedestrian Crossing, which aimed to encourage commuters to walk instead of drive.
The campaign was basically a large interactive illustration set on a busy pedestrian crossing.
The organization placed a large white canvass with an illustration of a bare tree on the street. Two sponge cushions that were soaked with eco-friendly washable and quick-dry green paint were then placed on either side of the street. Pedestrians who crossed the street would unavoidably step on the white canvass and leave behind green footprints that became the leaves of the bare tree. As more pedestrians crossed, more green footprints where left on the canvass–causing the tree to bloom.
The campaign was first carried out in seven main streets in Shanghai and then in 132 roads in 15 cities across China later on. The finished print was exhibited at the Shanghai Zheng Da CANART Museum. Via PSFK.com
