“In Perpetual Motion” follows adventure photographer Krystle Wright underwater where the roiling of the ocean sometimes makes time seem to stop, transporting her to another place entirely. To me, the underside of the ocean’s surface evokes storm clouds and memories of sitting at the bottom of the pool staring up at the way light played on the surface. How about you? What do you see when the waves roll overhead? (Video and image credit: K. Wright et al.)
