- 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
