Bluetile is a tiling window manager designed to integrate with the GNOME desktop environment. It provides both a traditional, stacking layout mode as well as tiling layouts where windows are arranged to use the entire screen without overlapping. Bluetile tries to make the tiling paradigm easily accessible to users coming from traditional window managers by drawing on known conventions and providing both mouse and keyboard access for all features.
The wmctrl program is a command line tool to interact with an EWMH/NetWM-compatible X Window Manager. It provides command line access to almost all the features defined in the EWMH specification. It's possible to, for example, obtain information about the window manager, get a detailed list of desktops and managed windows, switch and resize desktops, change the number of desktops, make windows full-screen, always-above, or sticky, and activate, close, move, resize, maximize, and minimize them. The command line access makes it easy to automate these tasks and execute them from any application that is able to run a command in response to some event.
xfburn is easy to use burning software for the Xfce desktop environment (but will work with others). It uses libburn and libisofs as a backend. ISO files can be burned, data composition created, discs blanked, and DVD-RW media formatted and deformatted. Common burning software features not yet implemented are audio CD creation and disc copying.
Sherman's aquarium is a screen saver, a GNOME panel applet, and a dock applet that provides an aquarium with fish and/or turtles. In applet mode, it can display lots of information, such as CPU load, temperatures, memory usage, and many other things. Both the applet and the screensaver are very configurable.
