To make everybody on your office jealous buy a binary watch.
It shows the time in a semi binary format. I think a true geek watch should show the number of seconds since epoch in binary, but a very few could translate that to time used in the normal world.
Thinkgeek is the obvius place to look for a thing like this but it seems like they have stopped selling it, but I found mine at NetOnNet, a swedish online shop. Buy the way, they monitor their systems with op5 Monitor.
