FractRoam

FractRoam is a real-time explorer for the Mandelbrot and Julia sets — and its heart is the autopilot. Press play and let it roam: FractRoam continuously seeks out the most visually interesting regions of the fractal and glides you through them, an endless, ever-changing tour you can simply sit back and watch.

Want to take the wheel? Pinch and drag to wander on your own, and recolor the whole scene with a tap. Everything is drawn pixel-by-pixel on your device's GPU, in real time.

FEATURES

• Roam autopilot — hit play and drift through a continuous, auto-discovered tour of the fractal

• Real-time Mandelbrot and Julia set rendering, GPU-accelerated and smooth

• Pinch and pan to explore yourself, or hand it back to the autopilot anytime

• Color moods — six hand-tuned palettes plus animated color cycling

• Share any view — a picture plus a link that reopens the exact same spot

• Fully offline — no account, no ads, no data collection

• A calm, full-screen interface — just you and the fractal

Whether you want something mesmerizing to get lost in, a generative-art source for textures and wallpapers, or a hands-on way to explore the math of self-similarity, FractRoam turns the Mandelbrot and Julia sets into something alive.

There's a matching macOS screensaver too — find it at fractroam.com.
