True, the demoscene produced lots of this kind of stuff also, but with as many different purposes and goals as similarities. I don't think of your effort or the video I linked to as being demoscene because they don't share the same ethos. Sting [2], and other big pop stars [3] played around with this kind of audio-video (sometimes interactive) stuff when people thought multimedia meant "CD-ROM" and FMV.
I think your effort here sits very comfortably in the context of these kinds of audio-visual efforts. Nicely done!
