wmsystray provides a system tray compatible with freedesktop.org's System Tray Protocol specification. Basically, it serves as a system tray that allows other programs to show icons in it. For example, if you enable GAIM's System Tray Icon plugin, wmsystray will display GAIM's systray icon. Its intended use is as a Window Maker dock app, though it will run in other window managers as well.
WMTimer is a dockable alarm clock for Windowmaker or Blackbox which can be run in alarm, countdown timer, or chronograph mode. In alarm or timer mode, you can either execute a command or sound the system bell when the time is reached. WMTimer is configurable through the command line or the GTK GUI.
