Gargantua Black Hole 3D

Takohi - タコ火

About this app

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.
