A 3D engine that draws in text.

CP437-Engine renders scenes with coloured light, shadows and traced reflections, using only text characters. There is no rendering library: projection, clipping, the z-buffer and analytic ray tracing are all written by hand, and the last pass runs on the GPU with WebGPU and a CRT effect. It began as synth-ascii-wallpaper, an outrun wallpaper drawn entirely in ASCII.

A toolkit for everyday TypeScript.

Hyrax is a general-purpose TypeScript toolkit with zero runtime dependencies. The core covers the small helpers most projects end up needing: number helpers like clamp and lerp, case conversion, a StringBuilder, null handling, and a seeded random generator that rolls tabletop dice, forks and saves its state, with output that is part of the public contract. DOM utilities and React hooks and components get their own entrypoints, so importing the core never touches the DOM. A CI check enforces that: it compiles a fixture that uses window and document against the core config and fails the build if that ever succeeds.

It has its own documentation site: a guide for each entrypoint, the API reference generated from the source, and examples that run the library live in the page. Every example is a test. The build type-checks them against the built package and runs the ones for the core, so an answer that goes stale fails it.
