Ivan Sutherlands The Ultimate Display

• Dont think of that thing as a screen, think of
  it as a window, a window through which one looks
  into a virtual world. The challenge to computer
  graphics is to make that virtual world look real,
  sound real, move and respond to interaction in
  real time, and even feel real.
