   I guess I could have duplicated the outer sphere, and then given it its 
green tint instead of using a metallic sphere.

  (I'm doing another <better> version right now with a red tint, but it'll 
be a couple of hours yet).

   Time is always against me Mike. I find Wings helpful.

   It's a normal function played around with, and increasing the IOR to 
1.55:

    sphere {
  <0, 3.7, 0>
  3

   material {
    texture {
      pigment {

        color rgbt <.7, 0.35, 1, 0.4>

      }
      finish {
        ambient 0
        diffuse 0.18

        reflection{ <0, 0.3, .55>

        falloff 5

          fresnel on
        }

        specular 0.2
        roughness 0.003
      }
      normal {
        function {
          f_ridged_mf(x, y, z, 0.1, 3.0, 7, 0.7, 0.7, 2)
        } 0.8
        scale .5
      }
    }
    interior {
      ior 1.55
    }}}
