58 * You will see three grey cubes, a blue sphere, and a path which
59 * circles each cube. The blue sphere is generating a constant
60 * monotone sound as it moves along the track. Each cube is
61 * listening for sound; when a cube hears sound whose intensity is
62 * greater than a certain threshold, it changes its color from
63 * grey to green.
64 *
65 * Each cube is also saving whatever it hears to a file. The
66 * scene from the perspective of the viewer is also saved to a
67 * video file. When you listen to each of the sound files
68 * alongside the video, the sound will get louder when the sphere
69 * approaches the cube that generated that sound file. This
70 * shows that each listener is hearing the world from its own
71 * perspective.
