Hi James,

Thank you for the nice style by circle size version.

When time permits, I'll add some style to the Doyle Spiral node, by arm, or position in arm.
Or gradients.
Adding an indexByArm output, and an indexByPositionInArm output might suffice?

There are two arm possibilities, "rows" or "columns" corresponding to p and q.

Maybe even rotation animation.

MoI scaling would move the two attractors apart.
Note that circle C of the Doyle cell is mapped and relocated from center (1,0) to center (0,0), with mapped A and mapped B circles still tangent.
For a different moebius transformation separation of the attractors, the formulas would have to be recalculated. I think this would be a scaling as well(?).

I'll have to try sphere replacement. Cannot remember if such a script was written yet.

p.s. It seems that one circle near -1 does not get colored?
