Albeit in a reverse rotational to reciprocal conversion order, shutter sequence is based on the principles of early 20th century radial aircraft engines, with a gearbox, crankshaft, articulating rods, pistons and cylinders. Instead of valves opening and closing, several protrusions on the ring gear activate rolling limit switches mounted along the edge of the gearbox. These switches trigger lights in sequence, as well as generating audio signals within a narrow spectrum of the harmonic series, tuned to the stepping frequency of the motor used to drive the shaft.
