I was thinking of something like this, but with Project Files instead. A huge list of project files from all over the place, whether it be remakes, light shows, anything. That way, you could categorize them, one of the categories being Lightshow. Idk, seems like it would be cool, wouldn't have to go digging for files anymore :> But back to the particular thing you were saying, it could be a massive like... gigabyte Ableton Pack, which you install into your user library, and you can just add in as many of the effects you want to you're light show.... I like it. I'd definitely be down to throw some lights together for something like this, I'll start saving the lights from my Animals cover I'm working on.
Apparently, I'm "Diplo Jr."... I ain't complaining.
