Via Boing Boing Gadgets, these are LED spray cans by the French artist Aissa Logerot, a project he calls Halo.

I think these are especially awesome because they’re a better execution of my own LED spray cans I built for the 2006 Burning Man project, “The Ephemeral Graffiti Wall.”  I built this project with my friends Jonathan Mayer and Erik Gilling.

The Ephemeral Graffiti Wall was a 40 foot long plywood wall painted with glow-in-the-dark paint.  One “painted” on the glow-paint using the LED in the spray can.  The pictures below show the spray cans I made for the wall, some of my original notes for the spray can design, and a picture of what “painting” on the wall looked like.  My friend Girts even riffed on the spray can, using a microcontroller to make a light printer.

Aissa Logerot’s lucite spray cans are gorgeous.  They also incorporate a feature I wanted in my own spray cans: a shake-to-charge mechanism.  I opted against this feature due to cost and time constraints, instead using 4 AA batteries and a marble for shaking effect.

I’m pleased to report that after 1 week on the playa and 3 years later, several of these “spray cans” remain operational, still with their original batteries.

Jonathan has a collection of photos on Flickr showing the wall from conception through execution and final destruction.
