Hi Dave,

I like his material too - like many other materials he made.
In the case Robert misses your post, look at the page for the original Povcomp
entry - here he describes the making of the texture
(http://www.povcomp.com/entries/137.php).

Based on his description, I constructed this material -

#declare p_map_metal = pigment {image_map {jpeg "colorful_pattern" gamma 2.2
map_type 0} scale 0.5}

#declare p_map_metal2 =
pigment {
 average
 turbulence 1
 pigment_map {
  [1      p_map_metal rotate 90*x]
  [1      p_map_metal rotate 90*y]
  [1      p_map_metal rotate 90*z]
 }
}

#declare fnPig = function {pigment {p_map_metal2}}

#declare N_Hammered =
normal {
 bozo
 normal_map {
  [0      dents 0.05 scale 0.01]
  [0.15   dents 0.05 scale 0.001]
  [0.3    dents 300  scale 0.0005]
  [0.45   dents 0.02 scale 0.01]
  [0.5    bumps 0.07 scale 0.01]
  [1      dents 0.05 scale 0.005]
 }
}

#declare T1 =
material {
 texture {
  pigment {p_map_metal2}
  normal {
   average
   normal_map {
    [1      function {fnPig (x,y,z).gray} bump_size 1 accuracy 0.001]
    [0.2    granite 0.5 scale 0.2 accuracy 0.001]
    [0.2    granite 0.75 scale 0.12 accuracy 0.001]
    [1      N_Hammered bump_size 1 accuracy 0.001]
   }
  }
  finish {
   diffuse 0.5
   specular 1
   roughness 0.003
   metallic
   reflection {0.4, 1 metallic fresnel on}
   conserve_energy
   brilliance 8
  }
 }
 interior {ior 1.43}
}
