Excellent!
Now that there's some working SDL, I can try to understand where things went off
the rails, and try to make some variations.
Maybe a nested Appolonian gasket, but also one with circles in between 2
straight lines (circles with infinite radius, curvature of zero, resulting in
"Ford circles)
Thanks so much, Michael!

And of course, because the Appollonian gasket is a foam, . . .
bubbles!

and with a nested gasket, we could do a sort of Sierpinski triangle.
There's some kind of transformation that makes them isomorphic.

I've updated my page and published the code (at the very bottom).

Just posting this here for reference.

Would be cool to apply this to the gasket to see what pops out - probably a
Sierpinski Triangle.
