Moltov Projector Media Cartridge

The Moltov Projector Media Cartridge , by Gabe Dunne, is a (fictional) weapon for Guerrilla media artists, allowing them to project words onto any surface, with a diameter of about 20 to 30 feet.

Once the cartridge is attached on a surface, the owner may call it via cellphone and reprogram the projection as desired. To remove the cartridge from the surface, the artist connects to it, enters a PIN, which will disengage the cartridge enabling its user to retrieve it. Multiple projectors may be linked to create a moving message across multiple surfaces. Other possible uses include the support to project images, and static projects of any shape.
