Century Caller by Paul Slocum

Century Caller, 2005
phone line and computer setup that when called, returns calls via caller ID after a minute, hour, day, week, month, year, decade and century from the time of the original call. Each call plays a short sequence of tones made with samples of Paul's voice. Gallery installation involves painting the phone number on the wall.

Call it and see for yourself.
If it's down again complain to Paul (paul(at)treewave.com).
