 The first set of AddPoints draws a large X and erases the centre.
 The following loop draws a set of nested points, alternating erasure and fill, which results in a set of concentric circles.
-The 2nd loop draws a web of lines and frames it using some final AddPoints.

+This one fills the map with solid land, and draws 3 circular erased points in it.
