Lovely shape !

Here's a way to make a sphere with your boxes:

#version 3.1;

#include "colors.inc"
#include "golds.inc"

#declare Cx = -pi;
#declare Step = pi/30;
#while(Cx < pi)
 #declare Cy = -pi;
 #while(Cy < pi)
   box {
     -<1, 1, 1>, <1, 1, 1>
     scale 0.04
     translate -y
     rotate <degrees(Cx), degrees(Cy), 0>
     texture { T_Gold_3C }
   }
   #declare Cy = Cy + Step;
 #end // while
 #declare Cx = Cx + Step;
#end // while

light_source { <-2, 1, -2> color White }

background { color Blue/2 }

camera {
  location -3*z
  look_at <0, 0, 0>
}
