This is a simulation of the artwork: Days Alive (Version 1.0) - 1992 by Mark Madel
Once you have your current days alive displayed on the object above, you can turn off the controls (with the gray button),
then reduce the browser window to make it part of your desktop as explained here;
then it will operate exactly like the artwork, changing the day count at the exact minute of your birth time (or when next turned on).
