You don't enecssarely need real comple imagery for VJ usage, sometimes it's just color blends and whatnot. This is one of the effects that I'd really like to have in my setup as it would be possible for me to use it (with tweaks) as either a 2D layer either in graphics or ascii art type, or reuse the data for 3D art.
It's specially for the animation of it that I'm interested (code wize).
