Larswm
larswm is a window manager for the X [window system] that follows the tiling window manager paradigm. Using ideas from the older 9wm window manager, it features automatic tiling and virtual desktops. It also borrows other ideas, for example a limited form of plumbing, from the Acme development environment. Objects are tiled into non-overlapping areas, instead of using windows that can be stacked, as this approach can result in lower memory and CPU requirements.
