A marvelous marble-based music machine

Michael Rundle at Wired UK:

The Wintergatan Marble Machine, built by Swedish musician Martin Molin and filmed by Hannes Knutsson, is a hand-made music box that powers a kick drum, bass, vibraphone and other instruments using a hand crank and 2,000 marbles.

The video of it in operation is amazing.
