The Mobile Broadcast Unit with L.A.S.E.R Tag System (LTS) is the latest Open Source, Weapon of Mass Defacement developed by the Graffiti Research Lab in the Eyebeam R&D OpenLab. NYC! This tactical tool allows any citizen, graff writer, artist or protester to use a projector, camera and laser to write, in real-time, on large-scale surfaces and structures from a distance of 100's of meters away. Citizens can post their art, messages and propaganda on a scale previously monopolized by advertisers, governments, major media, and other cultural tyrants. The BMU + LTS is self-contained and mobile, mounted on a giant trike. This unit has its own power supply, custom armatures and a 1200 watt audio system.
