A friend at work sent me an email about this machine (thanks Lyn!).
The email said:
"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 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."
Truly amazing, thought I'd share it with a few more readers.
