Satisfying WebGL physics demo that runs entirely client-side with no dependencies.
The repo actually implements an RK4 geodesic integrator in CUDA kernels to trace millions of rays and produce frame sequences — plus handy scripts to generate a Perlin accretion disk and preprocess NASA EXR star maps. It’s the sort of technical playground that shows real GPU know‑how and produces striking renders, but the experience is experimental: you must manually fetch assets, run preprocessing scripts, and there are no builds, benchmarks or accuracy notes to help anyone reproduce or compare results.
Persistent screen-edge glows replace annoying toast notifications for break reminders.
Terminal screensaver keeps Mac awake while cycling ASCII themes via a custom scene API.
Live multiplayer craps table with full betting UI—but it's a game, not a tool.
