a script for Norns loosely based on the motion of celestial bodies https://en.wikipedia.org/wiki/Barycenter

two bodies rotate around a central point, two rotate around those, two rotate around those to create 8 visible bodies. as the visible bodies cross the horizon notes are struck and sound is made. symmetry is maintained at a horizon of zero, offsetting the horizon allows for asymmetry
