The Ninth Column
Sound Gallery of Radio Free Berlin, 1999
In the middle of the four stories high main hall of “Haus des Rundfunks” (house of broadcast) stands a green glowing column of over 5 metres high and approximately 50 cm wide. It consists of illuminated computer-circuit-boards with their electromechanical components. Their quickly pulsating, percussive sounds, moving up and down over the whole length of the object, accentuate the verticality of the space with its eight pylons supporting the staircase. Moving along, the audience activates the sculpture through motion detectors. Lines of sound meander on the side facing the spectator. A complex software varies the density of impulses and the beginning and final points of the sound-lines as well as their speed and spatial apportionment.
