Music Makers

The attached video shows this incredible machine that 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 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. (Reference given by Aananthan)
