4Dwm
From Wikipedia, the free encyclopedia
4Dwm is a window manager normally used on Silicon Graphics workstations running IRIX. 4Dwm is derived from the older mwm window manager and uses the Motif widget toolkit on top of the X Window System found on most Unix systems.
4Dwm on IRIX was one of the first default graphical user interface desktops to be standard on a particular Unix computer system. Other X window managers that mimic the 4Dwm look and feel exist, such as "4Dwm" for IceWM.
