Fun fact: there were no computers involved in the making of 2001. They were too expensive at the time. All of the monitors in the movie were actually back-projected film screens. All of the wiredframe 3D models were literally wire models, painted white, filmed and then projected on the screen. Using back-projected screens meant 2001 had flat screens which still look modern today --as opposed to the bulbous CRT monitors used in Blade a Runner and Alien.
