This is one of the coolest things I've ever seen. Such ingenuity, such creativity...and it's all wrapped around a very good song, to boot. This machine inspired by steampunk principals uses marbles and mechanical energy in the form of a hand-cranked flywheel to follow a mechanical program that plays a variety of instruments. The creator, Martin Molin, uses levers to turn specific instruments on and off to flow through the different parts of the song, cranking that flywheel the whole time. I'm blown away. I hope you like it, too. The machine and the "band" are called "Wintergatan," and if you check out their YouTube channel, you can see lots of videos detailing the building process. When finished, it had 3,000 parts and used 2,000 marbles. A shout-out to my sister for the heads up.
