julia

An endless dive through Julia sets. Pick the complex constant from six presets or dial in your own, and a wayfinder hunts down a spot near the set's edge, dives toward it for a cycle, fades out, and begins again somewhere new. The dive is seeded, so one seed always takes the same journey, and the same math runs on the CPU or a GPU shader.

Dials

• preset offers six constants like -0.4+0.6i; custom frees cre and cim anywhere from -2 to 2.
• zoom magnifies each step by up to 1.05; cycle is a dive's length, 30 to 3000 steps.
• depth caps the iterations at 16 to 600; band stripes the escape counts into color and drift animates the palette.
• spin slowly rotates the plane; fade crossfades each cycle in and out.
• width and height size the frame up to 512 pixels; primary and accent are the two ends of the palette.
