The cube not only glows in response to sound, but also blinks and glows in a curve sometimes, regardless of the sound. How the cube glows can be controlled by sending sound commands. For example, in one scene, the cube blinks regardless of the sound, in the next scene, the cube reacts to low pitch sound and glows red. After that, the cube reacts to low pitch sound by glowing blue, middle pitch sound by glowing green, and high pitch sound by glowing red. Creating the cube object and designing the plan of commands is merely making a platform. There are many possibilities for which this can be presented. If one wants to enjoy such a media work using those commands and exchanging data, usually one needs a computer or a special interface device. However this work only requires speakers, and one can enjoy the results to the full extent. For example, you can input commands to an audio CD and the cube would respond fully to the sound. This work can be played using existing infrastructures.
