Brilliant interactive lighting installation; “Water Light Graffiti” by Antonin Fourneau made during his residency at Digitalarti Artlab. When the LEDs on the wall come in contact with water either by paintbrush, atomizers, fingers or anything damp they light up to varying degrees depending on the moisture. “Water Light Graffiti is a wall for ephemeral messages in the urban space without deterioration. A wall to communicate and share magically in the city.” The video below is by Digitalarti and music by Jankenpopp. You can see images of the wall being made on Facebook.
