Hard Drivin' is a kinetic installation created by Ivan Twohig, Benjamin Gaulon and Brian Solon. The title of the piece references Hard Drivin' a video game released in 1989. The game featured the first 3D polygon driving environment. The installation involves radio controlled (R/C) cars that physically react to short messages ('tweets') sent through the popular social networking site Twitter. The cars are placed on a 3d-like structure inspired by polygonal modeling. Anyone can participate by telling the cars to begin following another user, by sending a simple command inside a tweet
