Reply to Music/Visualization Engines - Where do they belong?

Hey everyone,

I just finished beta on this awesome music visualization engine that is basically fractals spun into acid using mathematical equations. Something that I am curious about is: how exactly is software like this uploaded and sold? I've tried just about every Google search imaginable and am at somewhat of a loss. However, every Google search I did inevitably led me to this community , so I thought I might throw out a line here.

Any thoughts?

Thanks!
