Many of us have a difficult relationship with the graffiti. There are those who loves them or hate them. But now things have changed.
From Wikipedia:

LED Throwies were devised by James Powderly and Evan Roth working together at the Graffiti Research Lab during a fellowship at Eyebeam OpenLab in 2006. The technology, like everything from the OpenLab, is open source and in the public domain. LED Throwies were designed as a new kind of graffiti art to be used on ferromagnetic surfaces like steel. Part of GRL’s original campaign involved distributing throwies to a group of people, who were then encouraged to throw them onto a metal sculpture called Alamo, located at Astor Place, Manhattan, New York City.

Are you redy to party? Let’s go to design!

Led throwies are a non-destructive way to do street interaction design. What do you think?

Why not add at our repository a mod to make the led throwies greener?
