Just three #while loops and two #if statements, plus a little 
pattern-based scaling.

Qs, Cs?

That looks really nice - what's the algorithm for producing the dendrites?

Thanks Chris.

Here it is, minus the extraneous pattern-based scaling:

#declare thk=.5;

union{
 #local Z=-20;
 #while(Z<=20)
  #local Y=-11;
  #while(Y<=15)
   #local X=-20;
   #while(X<=20)
    #if(rand(R)>.33)     
     #if(rand(R)>.33)
      box{ <-1,-1,-1>, <-thk,1,-thk> translate<X,Y,Z> }
      #else
       box{ <-1,-1,-1>, <1,-thk,-thk> translate<X,Y,Z> }
     #end
     #else
      box{ <-1,-1,-1>, <-thk,-thk,1> translate<X,Y,Z> }
    #end
    #local X=X+2;
   #end
   #local Y=Y+2;
  #end
  #local Z=Z+2;
 #end
 //rotate y*(35+180)+x*180
 pigment{rgb 1}
}

Very interesting light (one of my favourite topics) and the object is
original .. at least I have never seen it before!  The camera seems to be
orthographic, is that right? Very nice overall.

Regards,
Hugo

The light in the first image is a combination area_light+sky_sphere 
using radiosity. The camera is using the fisheye projection with a 
fairly low angle (something like 15).

Hi,

Great job! I'm interested in the part of the code for the floor. Could you
please post that part? I need a similar one for a picture I'm doing.

Thanks!


BR / Fernando

	Wow.  That is cool.  How did you do it?

Hi Fernando. The floor was just slapped in there for effect. Here's the 
code:

plane{y,-10
  pigment{
   bumps
   scale 5
   poly_wave .3
  }
  normal{
   granite -.3
   scale 10
   poly_wave .5
   accuracy .001
  }
}

Hello Nospam. The code for the cube is in my reply to Chris Johnson 
about this same image. The title of the message is 'A view from the 
inside'. Perhaps I should make a habit of dropping the scene file into 
povray-binaries.scene-files?
