You may have seen this one come through your Inbox recently, called “Fantastic Machine”. It humorously claims:
This 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. 97% of the machine’s 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. It is now on display in the Matthew Gerhard Alumni Hall at the University and is already slated to be donated to the Smithsonian.
Obviously CG, but no less cool. Check out the complete piece courtesy of animusic.com:
