The mathematics

About this system

Julia sets are the partners of the Mandelbrot set: fix c and ask which starting points z₀ remain bounded under z → z² + c. The shape of each Julia set depends entirely on the chosen c — connected dust, dendrites, or solid regions emerge as c moves through the complex plane. Each image is a high-resolution Julia set for a specific c, rendered with smooth-iteration coloring so the color gradient corresponds directly to escape velocity.

In the Fractal Series collection

The Mandelbrot set and its companion Julia sets live in the complex plane at the edge of order and chaos. For each complex number c, iterate z → z² + c starting from z = 0: if the sequence stays bounded, c belongs to the Mandelbrot set; otherwise, the escape speed colors the surrounding fractal boundary. Julia sets fix c and vary the starting point, producing connected dust, dendrites, or solid regions depending on where c lies. Both reveal infinite self-similar detail at every zoom level — you can keep magnifying forever and the structure keeps renewing itself. Every image in this collection is computed at high iteration depth with smooth-iteration coloring, so the gradients you see correspond exactly to how fast each point escapes.

z_{n+1} = z_n² + c, escape when |z| ≥ 2
