Well of course, many people do.
Openbox by default looks like an X root window -- a black desktop with no app
windows open. Right clicking on the root window (desktop) opens the root menu
which has some program entries.
There's no panel. Everything can be added and customized.
Obconf provides for some basic themes and lets the user change window
decorations. Install feh for image viewing and obmenu to edit the root menu.
Fire up the terminal to start apps on the command line, eg. 'firefox &'.
Openbox can be great fun.
