I started with Jaime's LightSys Space Demo scene and ended up with this:


//Begin Code

isosurface{  // Close moon

function{(x*x+y*y+z*z-1)+f_granite(x*2,y*2,z*2)*f_agate(x,y,z)*.05  
+f_agate(x*100,y*100,z*100)*.001 -f_agate(x*1000,y*1000,z*1000)*.0001}
                   max_gradient 5.057

                     accuracy 1/1000000

                   contained_by{sphere{0,1}}

                 scale .2 rotate <-90,-90,-90> rotate <0,35,0> pigment{rgb  
.2} translate <.48,.1,-.707>-z*.802
                 hollow
                 }

//End Code
