is it possible to have avs create visualizations from the line in, rather than a prerecorded source?

Yes, it is!
 

While running winamp press CTRL-L and then type "linein://" in the box(without the "")..

Have fun!

Yea, this works well for live events
 

Hook AVS up to some decks and then a projector - instant trippy fun.

Peace

Oh yeah!
 

speaking of projectors, that's all I'm missing now, anyone know of any really good deals (best I've found so far is around 1000$..) I'm gonna do the rounds of the pawn shops though, maybe turn up a real gem, i hope!

ebay? :p

yeah..
 

I looked on E-bay.. there wasn't much.. as a matter of fact, there was next to nothing.. unless I messed up and just didn't find them, therte a relatively few good deals on projectors on E-bay...

But.. My buddy's dad owns a big-as production company, and I asked him what about hooking me up with a projector, and his dad might sponsor me bylending me a projector to do a few parties (sweet-ass)..

He also told me he has at least one older but functional and perfect for my needs, projector that he might let slide at a really good price..

Buddies are the best!
