In college (1990) I had an idea for a musical metal sculpture.
   [I was REALLY gonna do it some day; now I know I probably
   won't]:
   IMAGINE:
   A large hollow copper globe, about 20 feet wide and tall.

   Dented all over, strategically, mathematically.

   Holes cut in. Strategically, mathematically.

   All tuned to produce pleasing chords and melodies when the wind
   passes by from various directions.

   I also have a sketch for a playable version of it too, with
   blowers powered by people on bicycles I think, and a series of
   pipes and chambers and valves and such. A completely human
   powered instrument. Or Wind powered. One... or the other. No
   computer, except perhaps in the initial calculations.

   The piece _could_ be programmed in, where flags pop up when it's
   time for each individual player to play their note via some sort
   of piano roll.... or they could devise some other sort of
   communication system.

   I also have a one-person playable, electronic, computer
   controlled version as well but to me, the human powered one is
   far more interesting.

   I'll never do it though, but I still love the concept I'm sure
   _somebody_ has done that kind of metal wind sculpture [copper
   was my choice... as the patina over time would detune it
   slightly, making it more interesting, but still requiring the
   occasional tuning]
