I’ve been using this retro flip style clock for my Mac recently. You can get yourself one over at 9031.com. I’m liking their retro site with the floppies etc. To install (if you use Mac), drag the .saver file out of the disk image and directly into the screen saver pref pane.
It’s certainly very useful to be shown what time it is full-screen whenever you’re not using your computer, but I’m still looking for a screensaver that just says the words “GO TO BED”.
