Guy Creates Music Machine With 2000 Marbles
 

All I know about marbles is that I used to fight with other kids over them at school. If you're killing time, take a look as it's a curiosity that's gone viral (over 16m views):

incredible engineering...

Thanks for sharing.

That's just... awesome!

that's pretty genious

where do you start? lol

That song playing is not coming from the machine, no way.
The music is absolutely 100% electronic.

You got Rick Rolled like a MoFo.

:2 cents:

something is obviously wrong with me because my first and only thought was "those aren't marbles"
