It is a hoax but a beautiful one.
THE HOAX GOES "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"
