From Graffiti Research Lab comes an innovative way to make a statement… LED Throwies. These are tiny LED lights connected to a small battery and magnet. What a way to add color to any ferromagnetic surface in your neighborhood.
“The goal of the G.R.L. is to technologically empower individuals to creatively alter and reclaim their surroundings from corporate visual culture in a time of aggressive, paramilitary policing tactics. G.R.L. agents are currently working in the lab and in the field to develop and test a range of experimental technologies for the state-of-the-art graffiti writer.”
You can find step-by-step instructions on how to make your own LED throwies at Instructables.com but make sure to watch the videos at GRL. Looks like loads of fun!
