Julia sets — one rule, infinite faces

The Mandelbrot fixes z₀=0 and asks which c stay bounded. A Julia set flips it: fix one c, and ask which starting points stay bounded. Every point of the Mandelbrot has its own Julia.

Drag across the little map below ↙ to pick c — the big set morphs live. Edge points → delicate connected dust; inside points → solid lakes.

c = −0.8 + 0.156i
