Sorry, screwed up the posting
. This is the desription of the apparatus in the clip.
"This is almost unbelievable ..... See how all of the balls wind up in
Catcher cones. 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."
