wobble rolling
bearings
each bearing obeys one line of physics — a = g·s·cos(φ − ωt) − c·v along its own radial groove — and nothing else. The plate's tilt precesses, so the downhill direction sweeps the disc and every ball's oscillation is phase-shifted by exactly its groove angle. The coordination is an artefact of the viewing, not of the balls · after @jechacas's kinetic sculpture: “a visual metaphor for how the sense of self is constructed — disparate elements moving in a particular pattern take on the appearance of being a single coordinated thing.” · ← more sketches
