Water Light Graffiti is an art installation made up of thousands of LED lights and designed by Parisian artist Antonin Fourneau. When water contacts the LEDs, they light up. Once the water evaporates, the art disappears.
Water Light Graffiti was in Poitiers, France for a few days at the end of July. A variety of people stopped by to put their designs on the board, some artists, some ordinary people. Some of the designs in this video are pretty impressive.
