Toorox is a Linux live DVD based on Gentoo which starts as bootable media using KNOPPIX technology. It is designed for ease of use, with a simple control center and a hard disk installer. It contains many applications and uses KDE, GNOME, or XFCE as a working environment. A live USB pen drive image maker is also present on the desktop. It is multi-lingual and contains the unstable branch of Gentoo (x86 and amd64).
DSWM (Deep Space Window Manager) is a tiling keyboard-driven X11 window manager. It is based on StumpWM code and is written entirely in Common Lisp and oriented for good usability with minimum startup configuration and good integration with Emacs. The project is under hard development, so it has many experimental features.
X Persistent Remote Applications (xpra) is "screen for X". It lets you run applications remotely (like ordinary X or VNC), but unlike ordinary X, these applications are "persistent" if you lose your connection, or even if you want to switch to another computer. Also unlike VNC, they are ordinary applications on your desktop managed by your window manager, not trapped in a box.
Wimpiggy is a library for writing EWMH-compliant, compositing window managers using Python and GTK+. The goal is to make writing a window manager as easy as writing a PyGTK application. This library can be used to build a trivial, working window manager in only about 40 lines of code.
DynamicWorkspaces is a small utility designed to dynamically adjust the number of workspaces (some call them virtual desktops) on your desktop. It will create or delete workspaces such that you always have one workspace free. You can also tell the program to keep at least n workspaces, no matter the number of windows opened (for example, to have at least 3 workspaces, plus at least one free). A common use for DynamicWorkspaces is to tell your window manager to launch it when you log in, so you just use it and forget about it.
