Absolutely awesome visualiser. Every time I open it, I'm glued to the screen for a while. Been following it since birth over at the ars forum, hot stuff. Particularly since the autopilot function was introduced, that just blew me away. I love the 'bloom' effect you seem to be getting with very high intensity areas, looks totally awesome.
How about a feature or mode where it autopilots but within a more specific range... like the type that blooms :)
Awesome work man. You made itunes that much cooler!
