On April 11, 1980, Tehching Hsieh began punching a factory time clock every hour for one year.
The rule governed everything: sleep, illness, meals and conversations. After each punch, he photographed himself in the same position. His hair grew as thousands of images accumulated, later becoming a six-minute film.
Hsieh missed 133 punches, often because he overslept. Those failures showed the limits of the body against mechanical time.
Time Clock Piece turned one year of life into a landmark performance and left behind only the clock, time cards and film.
