KBatt is a KDE panel applet to measure the battery
level of your laptop. It uses the APM interface
in your kernel to show a cute little display on
your panel: you can see the AC status, the
battery level, and how much time you have left.
wmspaceclock (or spaceclock for short) is an antialiased analog clock for the Window Maker dock to show the current local time. It has configurable background and configurable antialiased hand shapes (vector-based) and comes with more than a dozen themes.
