The first disc of this two disc set includes a segment frequently forwarded in emails as a "John Deer musical device" but is actually a computer generated musical Rube-Goldberg device. I bought this set for my wife, who is a music teacher for an elementary school, and her students love it. She uses the videos as an example for her "make your own instrument" lesson to spark creativity and imagination. The music does get a bit repetitive at times and does not make for amazing listening in and of itself but the video is what makes this program.
