Allin1 is a little dock applet for FluxBox and similar window managers. It monitors CPU load with a moving graph, memory and swap usage with histograms, battery and power status with histogram and icons, ethernet/PPP interfaces with icons and histograms (linear or logaritmic), filesystem space, and Seti@home progress.
FluxBat is an ACPI based battery monitor for the fluxbox window manager. It includes two parts: a daemon process that runs the update script and the update script itself. The whole software contains only about 100 lines of code and is easy to use by including only one line in the menu configuration file of fluxbox.
Fluxspace seeks to add advanced desktop functionality to pure window managers, like Fluxbox. The approach is to leverage existing tools, like Rox Filer and Idesk, with a flexible and modular Python API. Existing modules support desktop icons, panels, dockapp startup and swapping, and wallpaper management. Current features allow each workspace to have its own unique panel, icons, wallpaper, and running applets. Creating new Python modules is easy.
GOULD (GTK+ Objects Ultra Light Desktop) is an ultra-light desktop environment. Tt provides gpanel, a configurable desktop panel with a built-in shortcuts manager, gdisplay, an image viewer with a directory browser, gsnapshot, for screen, window, and region capture, and grdesktop, an rdesktop front-end.
