The Mobile Broadcast Unit (MBU) with L.A.S.E.R. Tag payload is an open-source Weapon of Mass Defacement (WMD) designed to enable graffiti writers, artists, activists and citizens to communicate in the urban environment on the same scale as advertisers, corporations and governments. MBUs provide 1200 watts of audio and 5000 lumens of video projection capability mounted on an industrial work tricycle.The L.A.S.E.R.Tag payload allows individuals to write their own personal communications and expressions with a 60 milliwatt green laser on industrial facilities, monuments, towers, bridges, city skylines and other hard and soft targets of interest. The design and custom software for the MBU and L.A.S.E.R. Tag payload has been released open source, without copyright or patent, into the public domain. Hobbyists, hackers and other private citizens are encouraged to freely use, modify and release their own MBU/L.A.S.E.R. Tag designs. Units currently exist in New York City, Mexico City, Barcelona and Budapest and can be “checked-out” for free from the G.R.L. resource library and arsenal for use by interested parties.
