Well more like I wish I were in knots.  I'm working on what I thought
 to be a relatively simple architecture scene, when the problem I have
 with drawing in real live hit the digits hard.

  Here is my base so far


  prism{
    linear_sweep // or conic_sweep for tapering to a point
    linear_spine  //linear_spline | quadradic_spline | cubic_spline |
 bezier_spline
   //note-I thought about changing this.  Would that help
  -0.0,   // height 1
  35.0,  // height 2
  3,  // number of points
  // (----the <u,v> points---)
  <-3,1.6666666667>,<3,1.6666666667>,<0,-3.3333333333>
  //objective: cause rotation along the vertical
  //axis so that the point on base twist
  //around "tower" by little more than one complete turn.
  //Twist                note-derived from help menu
  //  twist n turns/unit around x
  //replace "y" with "z*sin(x*2*pi*N)+y*cos(x*2*pi*N)"
  //replace "z" with "z*cos(x*2*pi*N)-y*sin(x*2*pi*N)"
  //am I suppose to use rotate command? N=?
  //what does this look like?
  texture {T_Chrome_1B}}
  //Still to come giving the "tower's" sides a concave curve(carve)
  //from top to bottom on all sides.    AAAAAAAAAAAAAAHHHHHHHHH!!!!!
