= activist tool: blue 10 mm light-emitting diodes (LEDs) powered by small batteries
Description
"The lights used on the banner are blue 10 mm light-emitting diodes (LEDs) powered by small batteries, commonly known as “throwies.” Throwies are open-source technology attributed to OpenLab and Graffiti Research Lab, developed as a means of creating non-destructive graffiti and light displays. This is the first time ever that they have been used on a banner." (http://freetibet2008.org/2008/08/19/bright-lights-spell-out-%E2%80%9Cfree-tibet%E2%80%9D-on-banner-in-beijing/)
