"S.I.N (Zone I)" (1995) by Marc Marc is a 'determinating sonic sculpture'.
A psycho-acoustic environment, S.I.N, by Marc Marc is a using 16 loudspeakers through which noise moved up and down the 7m high V2_ stairs.
During Wiretap 1.02, this 'Sound Moving' installation was installed. Along the stairs - deeply going downwards to the base floor of V2_ - the loudspeakers were installed. This line of speakers from the top down to the base created a zone of moving sound (two sounds of breathing, moving in two directions, up and down) that gave a special effect when walking the stairs.
