Since 1999 Cartwright has been recording the time of sunrise and sunset at his location. The 365 chimes in each set are cut to length based on the length of day at over a one year period. Changing latitudes, longitudes, elevations, time zones and seasons alter the local time of sunrise and sunset. Any deviation from a simple sine-like curve in the chimes indicates that there was a change in position on the surface of the Earth. The erratic nature of the 2003 chime set results from a year of almost continuous travel by bicycle and other means. A motorized striker sounds each tube in sequence from the beginning to the end of each year.
