[Thanks Tommy]OK Go - This Too Shall Pass - Rube Goldberg Machine version
But it isn't really a Rube Goldberg, I think. I've not been able to find many of Rube's original drawings, but I understand that it's a machine, in other words, the hardware fits together in a unit, not just a room, and it does a task. Whereas this sort of video, popular in recent years, is more like a scattered number of things happening in a long chain reaction. I don't know if there's a word for this thing.
