The »Republik der Geister, Republik of Spirits!« saw thousands of guests stroll though both universities‘ buildings discovering new things. The Republic Rooms (Republikräume) evolved through performances, art, concerts and music, light, sounds and installations. Students, instructors, alumni, and university employees of both universities joined forces to create this symbiosis. Relaxing sound oases, interactive colour games, acoustic room installations, mobile phone sounds performed, or an inaccessible den – guests were treated to a party that flickered into the next morning.
