Insane Musical Marble Machine Created by Wintergatan!

This Marble Machine is a handmade music box that powers a kick drum, bass, vibraphone and other instruments using a hand crank and about 2,000 marbles. With dozens of beautifully carved wooden parts, tracks, pulleys and funnels to collect and reroute the used marbles, it is a true work of art, and though marble machines as an art form of their own have a long and complex history, this is one of the best.
