dynamic tiling window manager

 spectrwm is a small dynamic tiling window manager for X11.
 .
 It tries to stay out of the way so that valuable screen real estate can
 be used for much more important stuff. It has sane defaults and does not
 require one to learn a language to do any configuration.
 .
 It is written by hackers for hackers and it strives to be small, compact
 and fast.
