For a few weeks, Antonin Fourneau has been working on the Water Light Graffiti project: a wall made of LED which light up when touched by water. After several tries, prototypes and material improvements, Water Light Graffiti was finally ready to take place for a few days in a public space, which happened to be Poitiers. From July 22nd to 24th, Poitiers inhabitants could discover and try Water Light Graffiti with the artist and Painthouse, a graffiti collective, invited for demonstrations.
