I used to work at a company that ran all their proprietary applications on x86 Solaris 10 and used OpenWindows (same greenish color scheme) all the way up to 2014 or so. I would have loved to have had that pizza app! :) I still have a fondness for the simplicity of OpenWindows and how well it it handled virtual desktops. It was really cool to use on quad monitor setups.
