FractRoam vs ARITAKA

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.

Astronomy for Astrologers ARITAKA bridges astrology and the celestial sphere. View the horoscope from four distinct perspectives to deepen your understanding of planets, the 12 signs, and the 12 houses. Why do the summer solstice Sun and winter solstice Full Moon appear at their highest point? Why do some signs rise steeply while others ascend obliquely? Why do certain house systems break down at high latitudes? Traditional textbooks rely on flat diagrams and formulas, but grasping three-dimensional celestial motion from two dimensions alone is an enormous challenge. ARITAKA serves as an aid to that understanding. ◆ Sphere View Displays planets, fixed stars, the 12 signs, and the 12 houses on the celestial sphere. Switch your viewpoint between inside and outside — like a traditional celestial globe, with orthographic projection. ◆ Sky Chart View Projects the horizon and meridian in 3D onto a two-dimensional horoscope. Read planetary positions near the horizon and meridian that flat charts cannot represent. Inspired by the astrology software Placidus. ◆ Stereographic View Freely navigate the sky and horizon to simulate planetary and stellar positions. Display and interaction design drawn from the astronomy simulator Stellarium. Includes rise, transit, and set times. ◆ Solar System View Projects the horoscope onto a 3D simulation of the solar system, offering an objective vantage point for the chart. ◆ Key Features · 7 house systems (Placidus, Regiomontanus, Campanus, Koch, Topocentric, Equal, Whole Sign, Alcabitius) · Tropical / Sidereal with multiple ayanamsha options · Fixed stars, constellation lines, and planet labels · 12 reference lines including horizon, meridian, prime vertical, ecliptic and equatorial grids · Direct date/time editing with VCR controls · Place search and saved observer locations · Screenshot sharing and URL sharing · Japanese / English interface A free Web version is also available at aritaka.com. The iPad version adds extra house systems, color customization, and unlimited saved profiles.
