The most famous recent photo of Dennis Ritchie has him sitting in front of a windows desktop, drawterm-ed almost full screen into a Plan 9 CPU server. (drawterm is the name of the program that allowed you to connect local resources to a CPU server and essentially present a window on your current desktop as a Plan 9 terminal)
