The Audio Grove installation by Christian Moeller consists of a circular wooden platform 12 metres in diameter, on which 56 vertical steel posts extend 5.5 metres up toward the ceiling. Each of the steel posts is connected to a touch-sensitive sensor system. This forest of vertical steel posts is an interface through which light and sound can be physically experienced and controlled. Visitors touching the posts can evoke a soundscape which always results in a harmonic whole whatever the conceivable combination of interactions. To accomplish this, the acoustical structures were perfected within a physical modeling system.
