There are no specific boundaries in this form of window manager. For example, if the user runs out of space in the lounge, he or she can walk out into the hall and create more windows on the walls of the hallway leading into the lounge. It is also easier to remember where all the windows are when they are associated with the real world. Part of this ease of memory comes from having to walk around the space, or at least turn one's head around in the space.
This window manager, called RWM, also provides means of making the back of the head ``transparent'', in a sense, so that one can see windows in the front as rightside-up and windows behind as upside-down. This scheme simply obeys the laws of projective geometry. Rearview windows may be turned on and off, since they are distracting for concentration, but they are useful for quick navigation around a room.
