Stephen Hawking or clock-making in general. This £1 million ($1.83 million) timepiece took seven years to completely construct, and the initiative was led by inventor John Taylor who designed it in tribute to John Harrison (only the world's greatest clockmaker, it's said). The bizarre Corpus Clock visually explains that it relies on grasshopper escapement to function, and to let you know that time can never be regained once lost, that beast on top actually gobbles down time every 60th second. Oh, and every hour, on the hour, the sound of a "chain dropping into a wooden coffin" is played to really pound home the "time is a destroyer" concept. Thanks for the reminder, Dr. Grim.
