Crakle form <1,0,0>  or whatever the form is, right?

In a similar vein, try this one:

global_settings {               
  assumed_gamma 1.0
} 

box { -5, 5
  pigment {
    crackle
    form 1.1*x  
    metric 4
    scale 2
    color_map {
      [.09 red 1]
      [.09 red 1 green .5]
      [.18 red 1 green .5]
      [.18 red 1 green 1]
      [.36 red 1 green 1]
      [.36 green .7]
      [.54 green .7]
      [.54 blue 1]
      [.72 blue 1]
      [.72 blue 1 red .5]
      [.9 blue 1 red .5]
    }
  }  
  finish {
    diffuse .4
    specular .3
    roughness .001
  }
  
  rotate 30 * y
}
  
light_source {<0,0,40> color rgb .4 shadowless}
light_source {<-80,80,-20> color rgb 1}
light_source {<80,80,-20> color rgb .2 shadowless}

plane {y,-5 pigment {color rgb 1}}

camera {direction 1.5*z location <0,10,-20> look_at 0}

The 1.1 helps scale the result of the distance computation to fit in the
0..1 range imposed by the color map.  I determined the specific value by 
trial and error, but there's probably a legitimate argument for it (possibly
that the fourth root of 2 is about 1.1...)
