  1. Hey, am I right in thinking you have speakers playing something like a sawtooth wave here? I’m imagining that the vertical spike of the waveform is the jolt that makes the movement, then the angled slope is the part where you shift your weight slowly back to center. Is that about right?

    And then you do a reversed waveform to move the paper in the opposite direction?
