An exhibition of the Schirn Kunsthalle in Frankfurt from 2009. The bar was motorized and let loose the roof of a now demolished structure nicknamed The Table next to the art institution. The bar was proppeled at 0.04km/h around the rooftop between the guests. Sensors at the front and back reverse the direction of the motor allowing for gentle collisions and back-offs with guests and handrails. There was a toy alarm to signal a collision.
The closing night was rounded out by live music performances from Bernhard Schreiner & Bernie and Dave.
