Ghostty Blackhole Landing page: s13k.dev/blackhole A black hole floating inside your Ghostty terminal. It starts small and grows to swallow your screen, driven by whichever size mode you pick: a built-in pomodoro clock (grow through the hour, demand a break, leave you alone once you take it), or token mode, where it tracks how full Claude Code's context window is in real time. Modeled on Eric Bruneton's black hole shader, which beam-traces Schwarzschild geodesics against precomputed lookup tables. A Ghostty custom shader is a single Shadertoy-style fragment pass with no custom textures, so the lookup tables are replaced by doing the physics live: every pixel near the hole integrates its own null geodesic through the Schwarzschild metric (the Binet-form acceleration , which gives the exact photon bending). Your terminal contents play the role of the lensed background sky. Nothing below is painted on — it all falls out of the ray tracing: What it renders The shadow — rays with impact parameter under spiral through the horizon and come back black. Text near the edge is stretched into the photon ring before it disappears; text behind the hole really is gone.
