Since I spent 37.5 hours rendering this thing, I thought I would post it. It
is wallpaper size but compressed pretty small, hope it doesn't offend.

Very good, in both size and quality.  The black&white turbulent gradient for
the surroundings might be confusing to those who wouldn't realize it's not
actually a texture on the object itself, but then maybe they also wouldn't
think about that.  And if it is a texture on that, excuse me please  ;-)

I put it there to make the slightly lighter reflection in the original
image. But I scaled it wrong and when I saw the reflections I left it that
way.

BTW, here's the macro, excuse the clunkiness, it's salvaged from some of my
first efforts.

///////////////   Begin CIRCLECOIL   ///////////////////

#declare TURNS = 8;          // total number of sub-loops
#declare RADIUSX = .25;    // mess with these to make oblong CIRCLECOIL
#declare RADIUSZ = .25;    // or wider coils // minor radius of CIRCLECOIL
#declare MRADIUSX = 1.25; // major radius of CIRCLECOIL
#declare MRADIUSZ = 1.25; // major radius of CIRCLECOIL

#macro CIRCLECOIL ( TURNS, RADIUSX, RADIUSZ, MRADIUSX, MRADIUSZ )

blob {

#declare I = 0+clock;
#while ( I < 1+clock )
//

sphere { < 0.0, 0.0, 0.0 > 0.5, 2
          scale < 0.5, 0.05, 0.5 >
          translate < sin(I*((2*TURNS)*pi))*RADIUSX,
                      0.0,
                      cos(I*((2*TURNS)*pi))*RADIUSZ >

          translate < sin(I*(2*pi))*MRADIUSX,
                      cos(I*(2*pi))*MRADIUSZ,

       }
///////////////////////////////////////  end Sphere

#declare I = I + 0.001; // decrease to make smoother but takes longer to

            } // end union CIRCLECOIL
 #end

object { CIRCLECOIL ( TURNS, RADIUSX, RADIUSZ, MRADIUSX, MRADIUSZ )
          rotate    < 90.0, 0.0, 0.0 >

Why not just use something like this instead:

translate vrotate(z, y*turns*360)*< RADIUSX, 0, RADIUSZ>

Or store the RADIUSX and RADIUSZ values in a vector, and do this:

translate vrotate(z, y*turns*360)*RADIUS

If you don't want the y value to go to waste, use it for the number of 
turns. :-)

    Because I never did figure out vrotate.

    But I will not let that stop me from -using- what -you- figured out 8-)

Vector keywords give me a headache... I prefer the former... I understand the
math much better...

BTW. Thank you Bill... =)

Hey, that's neat stuff.  Ever thought of uncurling or curling such things up
in an animation?  Yeah, you probably have....

I'm not much with that kind of thing myself, I did try to replace the original
way in your pov script with the vrotate and it didn't work out too well.  Or
it least the obvious didn't work out.  Unending learning process.
