Deep-zoom fractal explorer for Mac and iPhone
Infinite detail, live.
Frostwork flies you into the Mandelbrot set and its relatives as smoothly as a video, from the whole set down to views magnified more than 101000 times.
From the Spiral Galaxy to Edge of Numbers, which reaches 10998 times
A universe that never runs out of shapes.
Every view is computed as you move, so you can wander anywhere: spirals inside spirals, tiny copies of the whole set, lightning, seahorses and ships.
Fly freely
Pinch, scroll, drag and turn. The view keeps up at full speed and sharpens as you go.
Autopilot
Let Frostwork steer. It follows the most detailed edges, diving, gliding and drifting back out.
Images and zoom videos
Save any view as an image, or render a video that zooms from the whole set down to where you are.
Its own music
Listen to Frostwork's own endless soundtrack: twelve themes on piano, harp, strings and more, arranged live while you explore. Or choose calmer background sounds, with the same volume and mute controls.
Mac and iPhone
Made for Apple silicon: on the Mac with trackpad and keyboard, on iPhone at your fingertips.
Places worth the trip.
Frostwork comes with curated destinations, each a click or a tap away.
