Here's mine. I could've bumped it up and squeezed more cubes into each ring,
but I'm not a CPU sadist. 2 minutes 30 seconds at 800x600 with 0.1
antialiasing

//Lots of objects in little code
#macro circ (a)
  #declare i = 25;
  object {
    union {
      #while (i>0)
      box {-.07,.07
        pigment { color rgb .5 }
        translate 1*z
        rotate i*(360/25)*y
      }
      #declare i = i-1;
      #end
      #if (mod(a,10)=0)
      light_source {<0,0,2>
        color rgb <.2,.2,.6>
      }
      light_source {<0,0,0>
        color rgb <.2,.6,.2>
      }
      #end
    }
    translate (a/8)*x + 2*z
    rotate (360/40)*a*x
  }
#end

#while (j>=-140)
  circ(j)
  #declare j = j-1;

POV-Ray finished



(yes I use MegaPOV, I never bother switching back and forth since MegaPOV is
fully back-compatible)

I think this is an elementary example of how powerful lightsources are. As
you can see, there are only 58 lightsources in a scene full of thousands of
boxes and it looks fully lit.
