READ THIS DESCRIPTION BEFORE WATCHING THE VIDEO!!
Turn your sound on for this. This is really cool.
Read this first, then watch.
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.

Sorry....but that is a computer animation, not an actual mechanical
device.
