I don't think that any of the warps can create something out of nothing,
they really just push and pull pigment around in 3D space or wrap pigments
around on themselves. There's no sort of hyperspace, or 4th dimension that
they can pull color from if they're not present to start with.

You may be right. I haven't done that sort of thing. It might be worth 
starting a new thread mentioning interior or media in the title in case 
those versed in the dark arts of density maps are no longer following this 
thread :o)
