Bubbles

[Pauldelbrot]

Bubbles and mini Mandelbrots!

Dark blue points diverge. Aqua points go to zero. Points that do neither are black. The boundaries are strongly enhanced towards white with a distance estimator layer.

As usual, there is a 2048x1536 jpeg available at the link and a 2048x1536 png available upon request.
