Further proving that code is poetry (and that hardware hacking is absolutely awesome), “Water Light Graffiti”, created by Antonin Fourneau, is the result of what happens when street art meets geek culture.
In the creator’s own words, the piece consists of “a surface made of thousands of LED illuminated by the contact of water.”
You can use a paintbrush, a water atomizer, your fingers or anything damp to sketch a brightness message or just to draw. 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.”
