The Desktop
``The metaphor was just a way of explaining why some windows seemed
blocked by other windows; it wasn't an attempt to simulate a
real-world desktop.'' -- Steven Johnson
``An intuitive way to use the windows was to activate the window
that the mouse was in and bring it to the "top." ... The active window
constituted a mode, to be sure, but one could get to the next window
to do something in without any special termination.'' -- Alan Kay
