Swedish musician Martin Molin has made an incredible hand-made music box. It’s called The Wintergartan Marble Machine that uses 2,000 marbles that not only plays but is a work of art too.

A hand crank is used to move the 2,000 marbles to play a vibraphone, bass, kick drum and other instruments. Tracks, pulleys and carved wood parts route the marbles to play music.

He began making the instrument in the fall of 2014 and completed it in 2016.
