At first I assumed that it was a video of a real machine, as was claimed
in the accompanying text:

"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."

Then I noticed the skips, as if from splicing or looping, and wondered
if that was just due to clumsy editing, or if the video was of a CG
machine. But if it is CG, it's a dazzling display of synchronized programming.

In any case, Raphael and Doug, I, too, like the video for what it is: a
pleasing, captivating, visual pattern of movements, in concert with the
musical patterns being heard. Something like Disney's Fantasia? Real
or CG music machines, videos of them might become another art form?
