Store description excerpt

Reach out to everyday wonder, and feel the beauty of equations. A pocket-sized science museum. THREE EXHIBIT HALLS [Celestial Hall] Solar systems and galaxies running on Metal compute. - Solar System: 8 planets + Moon + Galilean moons + Titan, with real-time moon phases. - Milky Way: 19 named real stars (Sirius, Vega, Betelgeuse, Polaris, ...). - Big Galaxy: ~5000 stars on stable orbits around a supermassive black hole. Side view reveals the lens-shaped galactic structure. [Chaos Room] Deterministic, yet unpredictable. Four flavors of chaos. - Three-body problem: figure-8 orbit (Chenciner-Montgomery), Pythagorean (Burrau), random. - Double pendulum: Lagrangian mechanics, RK4 integration. - Lorenz attractor: two orbits 0.001 apart, diverging exponentially before your eyes — the butterfly effect, visualized. - Magnetic pendulum: which magnet captures it, mapped as a fractal across the entire screen. [Fluid Lab] Cloud simulation + AI Cloud Lens. - Three sliders (water temp, sky temp, humidity) generate all 10 cloud types. - Photograph the real sky — Gemini AI identifies the cloud type and re-creates the same conditions in simulation. FEATURES - iPhone and iPad (Big Galaxy is stunning on iPad). - Japanese, English, Chinese. - Each exhibit has a "Go Deeper" section with related books (Principia, Cosmos, A Brief History of Time, The Fractal Geometry of Nature, ...). - Explanation level toggle: Kids / Standard. - Zero ads, zero tracking. The only purchase is a one-time ¥300 supporter pack that unlocks unlimited AI Cloud Lens (free 5 uses per day). - Designed quietly, with care, to reach children and curious minds alike. May this become a starting point for reaching toward everyday wonder.
