FractRoam vs HoroClock

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.

HoroClock turns the real-time positions of the planets into a beautiful clock face — astronomy and astrology, alive on your screen. The hour and minute hands tell the time. Around them, the Sun, Moon, Mercury, Venus, Mars, Jupiter, and Saturn orbit at their true ecliptic longitudes, calculated from astronomical algorithms. LIVING STARFIELD Over 1,600 stars from the HYG Star Database glow in their actual spectral colors. Bright stars shimmer with a halo effect that intensifies after dark. The sky tint shifts in real time with sunrise and sunset at your location. During meteor-shower seasons, shooting stars streak from the correct radiant point. SERIOUS ASTROLOGY TOOLS • Tropical and Sidereal zodiac (Lahiri, Babylonian Fixed, custom SVP) • 4 house systems: Whole Sign, Placidus, Equal, Regiomontanus • Ascendant, Midheaven, Part of Fortune, Lunar Nodes • Toggle Uranus, Neptune, and Pluto on or off • Fixed-star display on or off YOUR LOCAL SKY HoroClock calculates the Ascendant and Midheaven from your latitude and longitude, so the chart reflects the sky above you, right now. A CLOCK YOU ACTUALLY USE Leave it running and glance at it throughout the day — the planets drift slowly along the zodiac, the sky color shifts, and occasionally a shooting star crosses the dial.
