Überorgan, 2000
Twelve bus-size biomorphic balloons, each with its horn tuned to a different note in an octave, make up a walk-in self-playing organ. A 200-foot-long scroll of dots and dashes encodes a musical score of old hymns, pop classics, and improvisational ditties. This score is deciphered by the organs brain (a bank of light-sensitive switches) and then re-interpreted by a series of switches and relays that translate the original patterns into non repeating variations of the score.
