  You should. They are difficult to understand at first, but once you master
them, they are really handy. You can make pretty nice effects with them.
  Just a quickie which I cooked in a couple of minutes:

camera { location <0,1,-1>*3 look_at 0 angle 35 }
light_source { <20,15,-5>, 1 }
plane { y,0 pigment { rgb .5 } }
cylinder
{ 0,y*.1,1
  pigment { rgb <1,.5> }
  finish { specular .5 }
  normal
  { wood 1 slope_map
    { [0 <0,1>][.5 <1,1>][.5 <1,0>]
      [.9 <1,0>][.9 <1,-1>][1 <.5,0>]
    }
    scale .3
    rotate x*-90
  }
}
