Around the same time, Douglas Engelbart used computer screens both as input and output devices. In 1968, Ivan Sutherland , with the help of his student Bob Sproull , created what was widely considered to be the first head-mounted display (HMD) system for use in immersive simulation applications. It was primitive both in terms of user interface and realism , and the HMD to be worn by the user was so heavy that it had to be suspended from the ceiling. The graphics comprising the virtual environment were simple wire-frame model rooms. The formidable appearance of the device inspired its name, The Sword of Damocles .

With our Used CDs, you can expect the disc to be free of all but the lightest of surface marks — clean, and not dirty at all. You can also expect the case to be clean (we often change the cases ourselves — putting fresh cases on Used CDs we handle) — and you can expect the booklet to be in good shape, unless noted otherwise. We will list any specific details/defects underneath the item — so look for notes on cutout marks in the case, stamps on the barcode, or details like that.
