Hi Bob,
     Thanks for your comments. I didn't think the 
left hand stars would be that hard, because in 
both cases they are "star till you see new 
neighbors", but maybe in the zia context it could 
get confusing.
      In your word document you mention the shadow 
phenomenon in the squares. In a Sicilian circle 
the clockwise and anti-clockwise progressing 
couples are separate groups. An similar thing will 
happen in a zia with four squares (enclosed in a 
box) connected by contra lines.  Assuming the 
progression out of the squares is to the right, 
the #1 couple in the top left square will dance in 
each square only once and will be traveling along 
the connecting contra lines thru the zia in a 
clockwise loop. All couples not in this loop will 
dance along the connecting contra lines the other 
way to then enter each square a total of 3 times 
(with possible excursions along attached contra 
branches), thus forming a  much longer loop 
progressing anti-clockwise.
    In your first post you mentioned grid squares. 
Does anyone have any references about these, or 
related formations?
Cheers, Bill
