Description:
X11 window manager inspired by Plan 9's rio
It provides a very simple and clean user interface. It is click-to-type. It uses the X11 font system (which, unfortunately, means no Unicode support). . 9wm does not provide virtual desktops, customization, key bindings, EWMH support, or compositing. It does not allocate any colors, which will be great news if you are stuck in 1993. . It is a great place to start if you are interested in writing a window manager from scratch: many folks have done exactly this.
