Sawfish
Sawfish is an extensible window manager using a Lisp-based scripting language. Its policy is very minimal compared to most window managers. Its aim is simply to manage windows in the most flexible and attractive manner possible. All high-level WM functions are implemented in Lisp for future extensibility or redefinition.
FEATURES: Powerful key-binding: Virtually every function provided by Sawfish can be bound to keys (or mouse buttons). Event hooking: For many events (moving windows etc.) you can customize the way Sawfish will respond. Window matching: When windows are created you can match them to a set of rules and automatically perform actions on them. Flexible theming: Sawfish allows for very different themes to be created and a variety of third-party themes are readily available.
