A window manager for bitmapped displays and Unix

A window manager for workstations with bitmapped displays has been developed. It exploits the inter process communication mechanism of the 4.2 Berkeley Unix system, and the DARPA TCP/IP protocols to support remote access to windows. One user level window manager process runs on each workstation; it tiles the screen(s) with windows, and manages a mouse, keyboard and pop-up menus. Client processes make remote procedure calls requesting the window manager to create or destroy windows, and to draw text and graphics in them. The window manager asynchronously requests clients to redraw their images when windows change size. “You will get a better Gorilla effect if you use as big a piece of paper as possible. ” Kunihiko Kasahara, Creative Origami.
