On the occasion of World Water Day , Unlimited BDDP , partner of the International Solidarity NGO , specialized in the coverage of basic needs ( including water supply), has created an unprecedented public event : to better detect the bystanders, the agency has designed a poster of a new kind , directly using the water as a medium. A wall of water events was set in the very heart of Paris and delivered messages for one week causing the awareness of pedestrians on the damage caused by the non-potable water in the world. The installation was created using Aquascript.
