Artist Antonin Fourneau has decided to shine a new light on the concept of graffiti. He has constructed a wall that has thousands of LEDs that have been programmed to react to moisture. Using this technology, Fourneau has created an interactive work of art that can be written or drawn on using spray bottles, sponges, or even your hands! His name for the project is “Water Light Graffiti”, and it was on display in France a few months ago. The video below shows a few examples of onlookers creating glistening designs just by dripping water on the large display. Digitalarti, the company that helped Fourneau create the wall, has a program for certain people to rent the luminous canvas.
