Fantastic Music Machine

A post over at learningIT , titled "Sound Art", sent me to this video:

"This incredible machine was built as a collaborative effort between the Robert M. Trammell Music Conservatory and the
Sharon Wick School of Engineering at the University of Iowa.
Amazingly, 97% of the machines components came from
JOHN DEERE Industries and More.. Irrigation Equipment of Bancroft, Iowa.
YES, farm equipment!

"It took the team a combined 13,029 hours of set-up, alignment,calibration, and tuning before filming this video, but as you can see, it was WELL worth the effort.
It is now on display in the Matthew Gerhard Alumni Hall at the
University and is already slated to be donated to the Smithsonian."
