Sometimes you just have to marvel and celebrate the amazing things people do just because they can. This clip was sent to me with the following explanation:
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.
Aside from being completely awe inspiring it's also (in keeping with my general machine theme today) a different view on what's going on when machines are at play. It's the view we never get when we're stuck inside throwing or catching all the balls.
