Each of the HörRoom projects uses the 'harmonic contents' of an existing exhibition space. The harmonics contents are singled out and then bound for exploration within an artistic presentation, which the audience is invited to experience directly. In the Kunsthaus in Wiesbaden, Germany, the HörRoom project was designed for visitors by having them interact with a "game instrument” that filled the entire space. Here, as the visitors make there way through the installation, the phenomena resonance and reflection gets conveyed poetically. Black elastic cords of different lengths are spanned through the space horizontally and vertically. These cables are used to mount various diverse instruments and a lighting system. Some instruments require two cables, as the instrument consists of two parts, i.e. beater and sound-maker. The lighting system consists of a small mirror ball, with a high-powered LED light illuminating it. When the light system by the vibrations of the cable is set into motion, the system sends showers of light fragments through out the room. The visitors themselves experience the same space as a listening room, by making their own way through the installation, and make it a collaborative experience by plucking one or the other cable to set appropriate instruments into vibration which combines into a group artwork.
