The next level of social media-powered graffiti has arrived in the form of the SMS Slingshot, a device that lets you virtually paints city walls with text messages that are automatically sent to Twitter.
A Berlin-based group calling itself VR/Urban embedded the guts of a cell phone into a slingshot with a tiny screen for typing text messages and a laser pointer for aiming accuracy. Once your message is composed it can then be "shot" onto any surface (in conjunction with a camera and projector mechanism pointed at the target surface). The results are instantly tweeted out to the world. While this amazing creation essentially blurs the lines between local and global street graffiti, it could also raise the stakes in the realm of street promotion in ways previously unimagined.
