kdelnk2wmaker is a converter which outputs data suitable for inclusion in Window Maker's menu from KDE links. The major difference from other such tools is that this one supports i18n and can output application names in your favourite language (if that information is included in the kdelnk file).
larswm is a modified version of the 9wm window manager that adds virtual desktops, automatic window tiling, and many other features designed to make it a highly efficient user environment. One of the design goals is that you should never have to manually shuffle windows around on the screen. Another is that it should use as little CPU time, RAM, and screen space for itself as possible.
lwmenu is a TCL/Tk program that displays an application menu at the current X pointer position. It was written in order to scratch an itch--namely that lwm (Lightweight Window Manager) does not have a built-in application menu. It can be also used for other window managers that either don't have their own application menu (such as lwm) or don't currently have a menu-method written for the Debian menu system.
Phluid is a window manager that emphasizes efficiency, speed, and beauty. It uses rasterman's Imlib2 library as the image/font rendering backend. It also attempts to be flexible and compliant with the ICCCM standard and gets a lot of its inspiration from the enlightenment window manager, but some of the initial code design is based on aewm.
