Fun with LEDs : light graffiti

I'm always fascinated by what designers and artists can do with LEDs.  Here's an example of an interactive art piece from artist Antonin Foruneau.

Water Light Graffiti, created in the Digitalarti Artlab

The "Water Light Graffiti" is 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.
