Nobody else seems to be posting one, so here one is :) It's an 
isosurface plane with repeated cosine functions inside a #while loop. 
Looks kind of like architecture in some way, terrestrial or not...

Questions, comments?

Here's the code:

isosurface{
  function{
   -z
   #local V=1;
   #while(V<60*2*4)
    +min(
     cos(atan2(x,y)*pi*V)/V*sqrt(x*x+y*y)
    ,cos(sqrt(x*x+y*y)*pi*V)/V
    ,cos(z*pi*V)/V
    )+.1
    #local V=V+V+.5;
   #end
  }
  accuracy .002
  max_gradient 5
  contained_by{box{<-1,-1,-1>,<1,1,1>}}
  pigment{rgb<.4 .7 .5>}
  finish{phong 1 phong_size 50 brilliance 2 diffuse .8}
}

Very interesting image you got there, it'll give me something to think 
about while I'm walking the dog thisafternoon, and thanks for the code.

Could be the top roof of a strange (extraterrestial?) culture temple.

    Clearly it's the entrance to a Dyson Sphere. I've seen dozens just like
it while Astral Traveling.

now that is good!

Okay, did a search on 'Dyson Sphere'. If my image were the entrance to 
one, that means the engineers used copper, because it's green.

Somebody does need to render a Dyson Sphere, though. Maybe a type 1 
(non-rigid), since that is the most likely kind to be created, although 
creating many different orbiting/static habitats can be a little 
difficult. Need to build a good macro for that....

If it was the entrance, it would be in vacuum, so the copper wouldn't 
oxidize. It could be they just painted it or used some exotic alloy or 
composite.

How about a criswell instead? Much more room, and you could lengthen the 
life of the sun by a few million years while you are at it.
A ringworld or a lot of ring orbitals seems more plausible though...

Actually, I was just recently thinking of doing a "hollow planet" type 
image with an artificial sun in the center...not exactly a Dyson Sphere, 
but close enough to make this surprising...

    No, it has some of the properties of copper, but it's a non-atomic type
material, with string-like nucleus and predetermined linear electron paths.

    I've rendered several different forms, including an animation of the
construction phase of a rather simplistic one. Maybe after I finish the wall
paper sized version of your isosurface I'm doing, I will re-run one of
those. Because, of course, I just finished erasing most of my renders last
week to make room on my HD.

    The problem with rendering Dyson spheres is that at the distance needed
to see any significant fraction of the object, all detail is gone.
