The past week or so I've seen the video a few times (on my timeline on Facebook) for: 'The Wintergartan Marble Machine' (Music box). It was built by Martin Molin, a Swedish musician. 'The Marble Machine' uses a hand crank & 2000 marbles to create the sounds (Drums, Bass & other sounds).
I have to say it looks quite impressive. Very clever.
Until next time
