Well the first attempts I did where using povman with a combination of
shaders I wrote and code I found online. This image was done using SDL code
I here in the forums.

#macro BTEX(BlurAmount,BlurSamples,ObjectPigment,ObjectFinish )
texture {
   average texture_map
    { #declare Ind = 0;
      #declare S = seed(0);
      #while(Ind < BlurSamples)
        [1 // The pigment of the object:
           pigment { ObjectPigment }
           // The surface finish:
           finish { ObjectFinish }
           // This is the actual trick:
           normal
           { bumps BlurAmount
             translate <rand(S),rand(S),rand(S)>*10
             scale 1000
           }
        ]
        #declare Ind = Ind+1;
      #end
    }
}
#end

Credit goes to the very smart person that wrote this code but I can not
remember names very well.

I have not tried the megapov blur yet.

The povman shader gives more control but is slower. With it I was able to
fade the reflection off based on distance from the object. Not sure yet how
to do that with any other version of povray. Will keep playing.
