Dossier #2 from the Graffiti Research Lab: the Electro-Graf. An electro-graf is a graffiti piece or throw-up that uses conductive spray-paint and magnet paint to embed LED display electronics. The following pages describe the materials and processes used to create the prototype indoor and outdoor interactive electro-grafs created in the lab at Eyebeam.

And then there’s LED Throwies ( to watch the video of the first campaign). These are an inexpensive way to add color to any ferromagnetic surface in your neighborhood. A Throwie consists of a lithium battery, a 10mm diffused LED and a rare-earth magnet taped together. Throw it up high and in quantity to impress your friends and city officials.
This is fascinating. I am so tempted to drag out my soldering iron….
