  • Create a NetLogo model, based on exm08.nlogo perhaps, that performs a vertical reflection of the fundamental region of a frieze.
    • Hint #1. The x coordinate midway between xmin and xmax is
      xavg = (xmin + xmax)/2
    • Hint #2. If a patch in the fundamental region has coordinates:
      pxcor pycor
      then it's pcolor should be copied to the patch at:
      (xmin + xmax - pxcor) pycor
