The Lower Austrian Provincial Exhibition "Mystical Waldviertel" in Ottenstein and Waldreichs in 2001 made use of a large number of interactive media stations. checkpointmedia was responsible for developing the majority of the media stations and the hardware and software. In one project, two sound installations, one of which has 16 channels and both covering several rooms, were conceived and installed in cooperation with Wolfgang Mitterer, self-designated sound artist and composer.
