Thanks!

You know, I didn't start to realize that until I made that larger shape in the middle more round. But when you mentioned using a circle, it clicked. :-)
I first had a copy of the more square outside shape, but discovered that it was re-enforcing a carry-over of the sharp corners.
As logic dictates: in the condition where all of the polar lines come to a point, you are essentially calling for a "circular arrangement".
