I ain't no fancy programmer, but I found this once: "Lex, on the other hand, is doing everything she can to help. She spots a terminal and proclaims, "It's a Unix system!" This, many people claim, is a flub. She is looking at a graphical interface, they say, and Unix is operated by command line. This will surprise a lot of you, but you can run programs with graphical interfaces on top of Unix. Hell, there's a Unix version of Adobe Photoshop. Incidentally, Lex is sitting down at a Silicon Graphics workstation running a program called 3D File System Navigator, which runs on top of Irix, an implementation of Unix." http://www.bigwaste.com/library/jurassicflubs/part 2.shtml
