Ordinarily electronics and water don’t usually go together too well, but that’s not the case for this public artwork Water Light Graffiti by artist Antonin Fourneau and Digitalarti Artlab.

For this project—which was set up in Poitiers, France in July—the artist created a surface embedded with thousands of LEDs which light up when brought into contact with water. You can use any damp surface like a wet paintbrush, your hands, a spray, a bowl, even a bucket. Splash it on there and once the water hits the moisture-sensitive surface the LEDs light up to provide you with your masterpiece.

Thanks to Kelly Keirn for today’s fodder.
