Abstract
A clock comprising concentric rings of slots slits for indicating time by fully illuminating an appropriate one of the slots. Full illumination is propagated from one slot to an adjacent slot by causing all of the slots in a ring of slots to briefly light up sequentially, thus causing a flash of light to propagate around the ring of slots, thus more clearly showing passage of a second, a minute etc as the illumination was switched from the one slot to the adjacent slot.
