A few years ago I curated an exhibition at the National Geographic Society called, "It's About Time." It was 4,000 square feet and had about 150 artifacts, including a few interactive devices. It addressed many aspects of time from the Big Bang to time in a bottle, including celestial time, geological time, natural time, biological time, intellectual time, measuring time, saving time, stopping time, buying time, managing time, relative time, time in navigation, standard time, atomic time, time in the arts, time travel, and musical time. It was extremely popular. When's your project opening? It sounds fascinating. Ceres
