We're in a downtown theater. The lights are dim and the curtains drawn. Let the show begin. But when we're at home, it's not quite the same. And so begins the challenge for those AV specialists who work in home theater.

If a room with an average dimension of 15 feet was covered with mirrors, light could reflect three million times and the images would still be inside our optical fusion threshold. On a practical basis, light would die out long before it could reflect three million times, so the entire optical process of distraction lies well within the visual fusion time period. We don't have to worry about optical echo problems. With light we only experience visual fusion problems, and a little paint or wall paper goes a long way to control them.
