To quote computer graphics pioneer Ivan Sutherland who said in 1965: "The ultimate display would, of course, be a room within which the computer can control the existence of matter. A chair displayed in such a room would be good enough to sit in. Handcuffs displayed in such a room would be confining, and a bullet displayed in such a room would be fatal." Sutherland's futuristic vision sounds just like Star Trek's holodeck!
