Expose the framework behind UI viz and music

[OrkoHunter]

github.audio uses events to generate UI bubbles and sounds. The events in this case are coming from GitHub. But there are several use cases where the events could come from a different system and folks might want a similar website to be up and running.

A finance company might want to hear the sounds of transactions.
Twitter might want to hear the sounds of activities on Twitter.

The framework behind this should be reusable and separated out from github.audio project :)
