Laser cutter motors play Super Mario theme

Jed from HackLab wrote code that tunes the motors on a laser cutter so that it plays music -- here it is playing the Super Mario theme. This is slightly too perfect, leading me to wonder if it's not just some video of a laser cutter with a flanged-out version of the theme cut into the soundtrack. But hell, I want to believe.

lazzor music!
