As mathematical a proof explains the argument of a math statement, the Proof Light's visible and connected mechanisms spell out its rotating function. The Proof lamp is spun remotely by the rotation of the cable it hangs from, meaning users can turn the lamp to project illumination on different parts of the room. The effect in practice is both a pleasant tactile experience, as well as a channeling of the user’s focus, illuminating small areas as if they were independent spaces themselves.
