You should at least give it another try for Dynamic Dreams and Static wallpaper. That way you can at least use the effects that are available in DeskScapes..
I'll call that, and bump you "Hybrid Dreams." All those are really nice and run quite easily on my old single core cpu / agp video card.
I've even played with creating a couple of Hybrids. Really pretty easy to do in terms of the Deskscapes part of it, but making the animation, even my little hacky ones, proved to be a real challenge. I probably did it "the hard way" Kind of fun though.
