From the README

A real-time, browser-rendered Schwarzschild black hole simulation built with Three.js and custom GLSL shaders. Feed it with your microphone and watch the accretion disk grow; go quiet and real Hawking evaporation slowly boils the horizon away: mass is a live tug-of-war, not a slider.

mic-driven accretion, no canned animation, no snapping

Zero external dependencies: pure Python standard library serves one self-contained page; Three.js loads from a CDN. Drag to orbit, scroll to zoom, and allow microphone access when prompted.
