Just playing around with the geology of basic loops and blocks, and thinking of
isosurfaces...

Great image, I always love a scene that shows off radiosity and the quality of
this one is great. I like the texture on the blocks also, is it just a normal
texture or are you using SSLT (I have not played with SSLT yet but this looks
better than a standard texture to me).

I like it.

What are the darker squares that looks like panels or something on two 
blocks just to the upper left of the image center?

Very nice.

I knew it reminded me of something.

Thanks Sean, yes the texture uses SSLT, which really smooths things out,
especially on the isosurface version I'm working on.

Here's a simple sky-emission-only (textureless & lightless) test render where
the superellipsoids are replaced with equivalent f_rounded_box isosurfaces
having a subtle granite/agate averaged displacement.

Bill, thanks for pointing those out - I hadn't really noticed them before. After
some head-scratching and test-rendering the scene at 5000px wide (with just that
small section selected for render) I finally isolated those as being some sort
of SSLT artifacts, but I can't really tell where they're actually coming from...
so, yeah, like Stephen said, they're  obviously "Doors to Erewhon".
