Yes !

I've tried several textures one very simple : texture{pigment {color
rgb<.8,.8,1>}}
Always the same

This image is one out of an animation set, an you can see the notches moving
and changing size just because the object is rotated !

Anyway here is the source :

#declare teta=texture{pigment {color rgb<.8,.8,1>}}
#declare tetb=texture{pigment{color rgb<1,.9,.9>} finish{reflection .95}}
#declare tetc=texture{pigment{color rgbf<1,1,1,1>}}


// create a smooth blobby shape
#declare Strengthval = 1 // (+ or -) strength of component's radiating
density
#declare radiuss = .45;
blob
{
  // threshold (0.0 < threshold <= StrengthVal) surface falloff threshold #
  threshold 0.61
     sphere {<0,.951057,0>, Strengthval, radiuss}
     sphere {<0,.425326,.850651> , Strengthval,radiuss}
     sphere {<.809017,.425326,.262866> , Strengthval,radiuss}
     sphere {<.5,.425326,-.688191> , Strengthval,radiuss}
     sphere {<-.5,.425326,-.688191> , Strengthval,radiuss}
     sphere {<-.809017,.425326,.262866> , Strengthval,radiuss}
     sphere {<0,-.951057,0> , Strengthval,radiuss}
     sphere {<0,-.425326,-.850651> , Strengthval,radiuss}
     sphere {<-.809017,-.425326,-.262866> , Strengthval,radiuss}
     sphere {<-.5,-.425326,.688191> , Strengthval,radiuss}
     sphere {<.5,-.425326,.688191> , Strengthval,radiuss}
     sphere {<.809017,-.425326,-.262866> , Strengthval,radiuss}
     sphere {<0,0,0>,Strengthval,radiuss/3 texture{teta}}
  sturm
  scale 2
  texture {tetb}
  rotate <clock, 2 * clock, 3*clock>

}

Thanks for taking time to answer
