Graffiti Research Lab at Ars Electronica
While I was in Linz, Austria for Ars Electronica, the Graffiti Research Lab put together a workshop to make as many LED throwies as they could and then organised a meeting in the town center to decorate the trams that run through the city. Unfortunately my video of the event seems to be corrupted but I’ve got one image of a lucky tram that got the GRL treatment. You should have seen the passengers of the trams faces when the crowd from Ars Electronica decended on them. You can see a some of the Graffiti Research Lab‘s other events and documentation on their website.
An LED throwie is a small, battery-powered light, attached to a magnet (usually with conductive epoxy or electrical tape), used for the purpose of creating graffiti and light displays. They were devised by the Graffiti Research Lab as a new kind of graffiti art to be used on ferromagnetic surfaces.
