Footprints green tree in China

Jody Xiong and the China Environmental Protection Foundation made this public outdoor campaign to remind people of the benefits of walking instead of driving. These amazing horizontal billboards are placed on streets at 132 crossroads in 15 different cities. Green paint is placed either side of the billboard so when people walk past they leave footprints on the billboard, like they were leaves on a tree.
They have estimated that 3,920,000 people have walked through the installation. The final pieces are going to be hung in several urban locations. What an excellent idea!
