A couple of years ago, a video made the rounds on the internet. (Strangely, I don't think it appeared here on The Automata Blog.) It was a 3D animation of an intricate musical system in which bouncing balls triggered notes on an assemblage of musical devices. It was pretty convincing. I think there was a bit of confusion in some circles as to whether the machine was a real thing or not. It wasn't, but now it is. The folks at Intel have used that video as inspiration to create a machine that does more or less what the one in the video did! That's what you see above.
For reference, here is the original video titled Pipe Dream:
