Art student’s 407-piece hand-carved wooden clock (2016)
Here is something similar ("useless" complex machine made from wood) that somebody made to create music:<p>"Wintergatan - Marble Machine (music instrument using 2000 marbles)"<p><a href="https://youtu.be/IvUU8joBb1Q" rel="nofollow">https://youtu.be/IvUU8joBb1Q</a><p>The video shows the details pretty well too, and the piece being played is of quite good quality. One can see that the machine can just play a pre-configured song, but the operator can add and/or change a lot while running it to create variations of that pre-configured song. The machine is programmable, so that song could be changed.
