subtle is a grid-based manual tiling window manager with a strong focus on easy but customizable look and feel. In comparison to other tiling window managers, subtle has no automatic tiling of the screen size in any way. Instead, windows are arranged according to positions inside of a grid. These positions are called gravities.
myOS is a minimalistic, OpenGL capable, GNU/Linux-based system without X. It is a bare bones Linux system, stripped of everything but the files necessary to compile and run OpenGL/C code. It has a simplified directory structure and a cleaned-up internal cross referencing. It has two available variants. myOSx-less fits within a 64 MB RAM disk and features a WebKit based on Trolltech's Qtopia demo Web browser. myOSx is oriented for X11, and its development tools are built around Trolltech Qtopia to produce applications based on the WebKit and for the framebuffer of the original myOS system.
Lobotomy involves many sub-projects oriented to experimentation about new design for human-computer interaction and, more generally, a new way for home computing. It involves a relational filesystem, a window manager, and many libraries, tools, and daemons to automatically extract and handle metadata.
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.
WnDO (formerly Fbdo) is a small suite of complementary tools for adding behavioral extensions to Gnome, Xfce, Fluxbox, and other window managers. WnDO offers a plugin platform for tweaking the desktop environment. It focuses on modifying behavior, rather than adding desktop widgets. It has minimal dependencies, other than Python. Included modules handle window alignment, simple window tiling, process management, wallpaper management, and custom keyboard shortcuts. Wallpaper management capabilities include per-workspace and randomly-selected wallpaper. It performs its own key grabbing in order to avoid interaction and conflict with the equivalent window manager facility. It requires CmDO.
Fitz is a window decoration for KDE that allows you to work (or play) faster. Unlike other decorations, it does not have a title bar above the window. Instead, it puts the buttons in the menu bar. As a result, it lets you get to a menu item by ramming your mouse into the top of the screen. If you click on the window frame, the mouse will jump down into the middle of the menu bar and Fitz will generate a click. This effectively puts the menu bar at the top of the screen like Mac OS does.
