   Here is a piece of code that produce some weird results, change the
lambda and scale to see how it affects the texture. I think I have seen this
in older POV vresions. Look in the binaries for the image.

#declare Black_mirror =
   texture {
      pigment {color rgb 0}
      finish {
         specular .8 roughness 0.005
         reflection {0.2,0.8 falloff 1}
      }
   }
background {rgb 1}
#declare Povray_Logo =
merge {
   difference {
      cone {2*y, 1, -4.002*y, 0 }
      sphere {2*y, 1.4 scale <1,1,2>}
    texture {Black_mirror}
   }
   difference {
      sphere {0, 1 scale <2.6, 2.2, 1>}
      sphere {0, 1 scale <2.3, 1.8, 2> translate <-0.35, 0, 0>}
      rotate z*30 translate 2*y
    texture { pigment_pattern { bozo color_map {[0 rgb 0][1 rgb 1]} scale .3
turbulence .17 lambda 8.4 octaves 12 omega .9}
    texture_map {[0.0 Black_mirror]
    [1.0 finish {specular .7 roughness 1/125 metallic .35 reflection
{0.2,0.4 falloff 2.05}}]}}
   }
   rotate <0, clock*360, -25>
   translate <-0.5,-0.35,0>
   scale 1/4
}
   sphere {2*y, 1
   finish {specular .75 roughness 1/14 metallic .35 reflection {0.2,0.8
falloff 1.5 metallic .05}}
   pigment {red .28}
   rotate <0, 0, -25>
   translate <-0.5,-0.35,0>
   scale 1/4
}
camera {
 location <0,0.01,-2.075>
 look_at 0
}
light_source {
 <3,5,-4> rgb 1
}
object {Povray_Logo}
