Same twirly shape as Twirl I, again... totally different look, thanks to the bizzaro reflective, iridescent, splotchy paint job. Maybe this is what it looked like before all those geometrically-minded termites got their bughands on it.
Tech notes: The shape derives from a twirl/vortex combination done with Photostyler. Then, I used it as a grayscale to height map. None of those strange incised designs are actually part of the terrain -- they're all a result of really funky, deep bumpmapping.
