Long time beta tester Jordan Laws sent me this video mix he had put together (rather well if you ask me) using Video-SL. This video really shows how you can benefit from doing some pre-production on custom visuals.
I can imagine if I were to see this at a gig, it would distract me from dancing and I'd stand there staring at the screen, kind of half waving my arm, hypnotized by the visuals. Way to go Jordan. Check out the video:
