UC 7 - Audio / Music Visualization

I took a quick pass at use-case 7 and wondered if anyone had
thoughts/comments?

UC 7: Audio / Music Visualization

A user is playing back audio or video media from the webpage of their
favorite artist or a popular online music streaming service. The webpage
presents a graphic visualization layer that responds to the music in
real-time that the user may enjoy in a leisurely setting such as: at home,
a bar/restaurant/lobby, or traveling with an HTML5 capable mobile device.
The visualization layer is written using complimentary web technologies
such as the WebGL Canvas, where 3D objects are synchronized with the audio
and mixed with Video and other web content using JavaScript.

The user can control elements of the visualization using an interface
provided by the webpage developer. The user can change the colors, shapes
and tweak other visualization settings to their taste. The user may switch
to a new visualization modes: changing from a spectrum-analysis view, to an
abstract 2D or 3D visual view, a video overlay, or a mash-up of web-content
that could include all of the above.

The webpage provides the user with the ability to control the buffer size
of the underlying Audio API: this allows users with slower machines to pick
a larger buffer setting that does not cause clicks and pops in the audio
stream.
