Gargantua Black Hole 3D

A real-time black hole on your wrist. Gargantua renders a live, GPU-computed black hole on your Wear OS watch, inspired by the real physics of Schwarzschild black holes. This is not a static image: every frame is computed live on the watch. Light rays bend around the event horizon (geodesic gravitational lensing), the accretion disk rotates around a pure-black core, and the relativistic Doppler effect tints approaching matter blue and receding matter red — just as real physics predicts. OPEN IT AND WATCH • Real-time black hole animation with gravitational lensing • Pure-black event horizon framed by a glowing accretion disk • The screen stays on while the app is open, so the animation keeps running LOOK OPTIONS • Cinematic or physically-exact Schwarzschild look • Fast (battery-friendly) or full (maximum quality) engine EFFICIENT • Standalone Wear OS app — runs on the watch, no phone required • Rendering stops as soon as you leave the app, to spare the battery Open Gargantua whenever you want a living black hole on your wrist.
