Over the centuries, man has developed wonderful and intricate instruments that would delight our ears and pluck at our heartstrings. But what if you could somewhat undo all that and replace them with marbles? Sounds insane? That is somewhat the quest that musician cum inventor Martin Molin of Swedish musical act Wintergatan has taken upon himself to conquer, a quest that took him 14 months to finish. Fortunately for us, and maybe for him, the end result is just as astounding as the concept of a marble-driven music machine is.
