Rheotomic grid/surfaces

Hi,

A while ago Daniel Parker kindly shared a component named Rheotomic surfaces, I'm wondering if anyone can help me to work with it.

I'm trying to get to the circle packing pattern for the base grid for CA based agents. The problem is since the lines start from a square shape center they create redundant intersections. Is there a way to have circles in the center like Phyllotaxis, and have clean intersection, where all related lines meet at one point?
