A round space probe with antennas and rings, its blue LCD showing the hours,
minutes and seconds, with the date underneath. Red markers travel around the
outer rings.
The small figures above the time can count how long the screensaver has been
running, which is how long you have been away from the computer.
The probe is part of an experiment with relativity: when it comes home it
will be checked against the time standard Luma. For its
earthbound cousin, see Plate.
