Graffiti art can make the urban landscape way more beautiful and interesting, but some people object to permanent decorations on their buildings. Solution: Water Light Graffiti, by artist Antonin Fourneau, working in residence at Digitalarti Artlab. His wall of water-sensitive LEDs allowed visitors in Poitiers, France to create temporary masterpieces using waterguns, spray bottles, hoses, or just by throwing water out of a bucket.

This one in particular turned out great — an homage to the city of Poitiers and its landmarks.

Water graffiti makes the city beautiful, the city makes water graffiti beautiful … call it the water cycle. No, wait, that’s a thing already.
