About

An LED throwie is a small LED attached to a coin battery and a rare earth magnet (usually with conductive epoxy or electrical tape), used for the purpose of creating non-destructive graffiti and light displays. Artists throw individual LEDs onto a metallic object, like public sculpture or road infrastructure, which itself acts as a canvas. LED throwies were invented in 2006 by the artists Evan Roth and James Powderly, the founder of Graffiti Research Lab[11] at Eyebeam Atelier open lab New York City. After Graffiti Research Lab posted the instructions how to make a throwie on Instructables,[11] throwies went viral on the Internet and could be found in advertising, were for sale as DIY kits or further developed by other artists and hackers worldwide.
