Marble Machine, a music instrument using 2000 marbles — and Technic parts for programming

Some of you may have seen this video by now, as it went quite viral last week.

But even if you have seen it, you might wish to revisit it once more, as chances are you haven't even noticed that the wheels it uses for programming use LEGO Technic beams, and the actual programming is carried out using Technic pins.

The designer explains it in greater detail in his How It Works videos.

(Viewer discretion advised: he keeps calling the pins "nails", and in How It Works Part II, a severely damaged pin is shown in closeup while some design flaws are discussed that lead to just that damage. Not for the faint of heart.)
