Jody Xiong of DDB China in conjunction with the China Environmental Protection Foundation created this wonderful outdoor campaign to create a subtle visual reminder of the environmental benefits of walking versus driving. The canvas was placed in the middle of busy pedestrian crossings in Shanghai. On either side of the crossing were sponge cushions soaked in green environmentally-friendly washable and quick dry paint. As pedestrians crossed their shoe soles were imprinted with a small amount of green paint, leaving behind a trail of leaf-like footprints. Each green footprint added to the canvas like leaves growing on a bare tree. Awesome work! [source]
