Unlimited Fractals

Explore fractals at extraordinary depth.

macOS iOS iPadOS

Dive into the Mandelbrot set with precision that grows as you zoom, preserving fine structure far beyond ordinary floating-point depth.

Deep zoom, in and out

• Scroll or pinch to zoom, drag to pan, and hold anywhere to dive — steer as you fall by moving while you hold.
• The view center and zoom retain as many digits as the current depth needs, keeping fine structures sharp instead of dissolving into blocks.
• GPU rendering and perturbation theory keep navigation responsive at extreme depths.
• Zoom back out from any saved location without losing its coordinates.

Fractals across six families

• Escape-time — the Mandelbrot and Julia sets, plus the Burning Ship, Tricorn, Buffalo, Celtic, Phoenix, Newton, Nova, Magnet, and Multibrot.
• Iterated function systems & L-systems — the Barnsley fern, Koch snowflake, Sierpinski triangle, Pythagoras tree, dragon curves, Hilbert and Gosper space-filling curves, and Penrose tiling.
• Strange attractors — Lorenz, Rössler, Aizawa, Thomas, Chua, Clifford, de Jong, Pickover, and the full run of Sprott systems.
• 3D fractals — the Mandelbulb, Mandelbox, Menger sponge, Kleinian, quaternion Julia, and more, ray-marched and free to orbit.

Make it yours

• Open any Julia set — ⌘-click a point on the Mandelbrot set and its Julia set opens instantly; step back just as easily.
• A coloring studio — smooth gradients, crisp distance shading, embossed 3D lighting, stripe and triangle-inequality averaging, and binary decomposition, over palettes you can shift, densify, and randomize.
• Tune the detail — raise the iteration count to pull structure out of the deep, color the interior, and switch on 2× or 3× anti-aliasing for the final frame.
• Save your spot — bookmark a location by its exact coordinates, paste one in to jump straight there, and share it as plain text.
• Export a poster — save the current view as a full-resolution image.
