The director, Stanley Kubrick, was always looking for new and innovative ways to shoot scenes. He created his own low-light movie lenses for "Barry Lyndon" so he could film by the feeble light of candles. His work on the Star Child finale to "2001" was an incredible labor of love in the pre-CGI world of movie-making.
The Danny Riding his Big Wheel through the Overlook sequence in "The Shining" was one of the first uses of what came to be Steadicam operation. Kubrick hired the man who was working on the camera that could move through a scene without bouncing or jiggling, fitted him with a harness, and he followed Danny* through the hotel, recording the different sounds as Danny traversed hardwood floors and carpeted areas. Today's technology makes the scene seem pretty ordinary, but at the time it opened up a whole new world of cinematography and camera "magic."
*Kubrick chose Danny Lloyd to play the child Danny in part because the child actor wouldn't have to learn to respond to a different name. Lloyd didn't realize until years later that he had been in a horror film.
