So I ran a little program to generate MIDI files for the daily chimes for all ten thousand years of the Clock of the Long Now. I made one file for each year.
Oboy! It added up to about 270MB, and it takes a full year and nine months to listen to it all.
Though I'm particularly fond of January 07003 (which is on the Eno CD), I'm sure there's other sweet spots in those ten thousand years.
