Okay, I'm going to assume this is pretty much it until you say otherwise:

#macro MazePigment(Pig1,Pig2) 
  #local Pig3=pigment {
    gradient x 
    pigment_map {[.25 Pig1][.25 Pig2][.75 Pig2][.75 Pig1]} 
    warp {repeat x} scale sqrt(2) rotate 45*y  
  }
  function { noise3d(floor(x)+.5,floor(y)+.5,floor(z)+.5) }
  pigment_map {   
    [.5 Pig3 ]
    [.5 Pig3 rotate 90*y ]
  }
#end

camera {location 80*y sky z look_at 0}
light_source {80*y rgb 1}

plane {y 0
  pigment {
    MazePigment(pigment{color rgb <.5,.5,1>}, pigment {color rgb 0})
  }
}
