It's probably not a breakthrough, but I'm pretty proud of my find.
I use winamp and I have just been getting into skinning and programming buttons to events... While millin around in the events I saw the one under skins/music/ named start visualization. To me this sounded like it would start the normal winamp vis, so I starting looking up a cool vis for winamp. I found one and installed it. Went to play with it and I realized there is already one there that comes with winamp. I set it up and set up a button on xlobby, works like a charm.
If you're into visualizations and aren't into downloading a bunch of add-on crap that needs xlobby plugins and winamp plugins and all that, just set up a button that triggers the event "SKINS/music/start visualization". You'll have to set up the vis outside of xlobby so winamp knows what to start. Personally I like the "sexy voiceprint analyzer" or whatever it is. It'll pop up full screen and then hit the button you set up for the vis again and it'll disappear.
If you haven't noticed I'm a little long winded, but thanks for bearin with me.
