I am a pro VJ, and will use this at shows, so I can say -

This is indeed a collection of "Concert Quality Visualizers" that you can run automatically, or under manual control.

What I'd like is MORE detailed controls that you can enable
- over general color, brightness, etc.
and a few variables of each particular display
That would get the 5th star! ;-)

I have had it crash a couple times.
and though you can switch pages quickly
your texture mapped image may not update immediately?

Overall,
This is a great value for the money,
and it runs pretty much "plug and play"
for dance club style visuals.

Just a little bit more control would make it perfect!
