This is very similar in concept to the Voronoi pattern, and indeed, if the
"annular rings" are fine enough, one gets the visual impression of Voronoi cells
filled with a concentric ring pattern.

I just did this for fun, to illustrate a practical pattern to use for ripples in
water, malachite, rhodochrosite, wood, "jawbreaker" candies, etc, and to
implement an example that makes use of splines, loops, pseudorandom numbers, and
a discrete set of "basis functions" that are evaluated "en-masse".

Enjoy the "bubbles".

(Speaking of which, this could be a fun one to apply iridescence to...)

I'd have to think about how to vary the "radius" of each seed point, and then
apply the true bubble intersection formula to get a nice foam cross-section.
Foam isosurface, anyone?
