Another 'spatial' normal{} image using the following code:

#declare Nrml_0 = normal {
   //spatial type 0 bump_size +0.3  // Left
     spatial type 1 bump_size +1.5  // Right
     warp { repeat x offset 1/3 flip y}
     warp { repeat y offset 2/3 flip z}
     warp { repeat z offset 0/3 flip x}
     rotate <+22,+44,-43>
     warp { repeat x offset 0/3 flip y}
     warp { repeat y offset 1/3 flip z}
     warp { repeat z offset 2/3 flip x}
     rotate <-33,+22,-11>
     scale 1/17
}
