Swedish inventor and musician, Martin Molin has created the mind-bending Wintergatan Marble Machine, a complex Rube Goldberg machine that synchronizes 2000 falling marbles to play various instruments. The instrument contains a full xylophone, various drums and even a Hofner Beatle Bass. A complex series of pegs on a wheel releases the marbles according to Molin's tedius programming. (The concept is very similar to a simple musicbox...except a lot cooler!)
Notice how Molin keeps the machine running while still playing the bass with his left hand!
Molin has documented the building process in a series of videos on his website.

Way cool. Except those aren't marbles, they're ball bearings. Except the black one(s) (which may be a painted ball bearing).
What a talented man, absolutely amazing!
I have to share this with my students.
Hahaha. Love this thing. Yeah the guy is far out.
