The South by Southwest aerial vandal was named "Tyrone the Drone." In a slickly cut video by Chaotic Moon Studios, the makers of Tyrone, three men bike to the places they plan to tag. Then, through a confusing application of a wall-mounted sensors and a phone app, they mark walls with drone-delivered paint. Tyrone the Drone promises a stencil mount, a silly string configuration, and ultimately a flamethrower option (is fire the new graffiti?). Each payload works roughly the same, with an aerosol can carried underneath the drone and activated at the press of a button. For the flamethrower, the aerosol is hairspray, fired over a pilot light. From Chaotic Moon's website, it's hard to tell how much of Tyrone the Drone is serious or in jest, but the demonstration indoors at SXSW showed off silly string and flamethrower mounts, so if it's a joke, Chaotic Moon Studios is at least committed to the execution.
