I had a lot of fun listening to music in winamp when I was younger with milkdrop. But I think my tastes have changed now to where I prefer visualizations with more concrete imagery and variety instead of the usual variations of abstract effects (they are still dope as hell though).

I tried to design this app with that in mind, but I definitely see why some people don't find them this style of visualization to be interesting. Maybe someday someone will put some serious effort into bringing the demoscene-style visualizations into the modern era?
