Rendering black holes with Haskell

Rendering black holes with Haskell launched on March 12, 2016 with 88 votes, #593 of 4,409 launches that month and more than 95% of that year's launches. The site was still online in September 2026, 10 years on.

In plain words

This project renders visualizations of black holes using the Haskell programming language. It's designed for people interested in physics simulations and functional programming. The work combines theoretical physics with Haskell's computational capabilities to create black hole imagery, making it suitable for developers and enthusiasts exploring how functional languages handle complex mathematical visualization tasks.

    Physically accurate black hole you can put in your roomJul 2026 · blackhole.plav.in · ▲477

    We have a black hole at home — with actual relativistic physics, live in your browser. I'm Sasha (Alexander) Plavin, an astrophysicist at Harvard's Black Hole Initiative studying quasars and black hole environments. I work with raytracing/radiative transfer simulations professionally, and wanted to make one anyone can play with — so I built this app. Put the black hole onto your screen (any browser), or directly into your room with AR or VR (requires WebXR, for example Chrome on Android, or any VR headset). When looking around, pay attention to unintuitive relativistic effects: rays…

  • A physically-based GPU ray tracer written in JuliaFeb 2026 · makie.org · ▲198

    We ported pbrt-v4 to Julia and built it into a Makie backend. Any Makie plot can now be rendered with physically-based path tracing. Julia compiles user-defined physics directly into GPU kernels, so anyone can extend the ray tracer with new materials and media - a black hole with gravitational lensing is ~200 lines of Julia. Runs on AMD, NVIDIA, and CPU via KernelAbstractions.jl, with Metal coming soon. Demo scenes: github.com/SimonDanisch/RayDemo

  • Factorio Blueprint Visualizer2025 · github.com · ▲450

    Hey there, I'm a big fan of the game Factorio and the beauty of factories in the game. That's why I created a website to artfully visualize Factorio blueprints a few years ago. With the new 2.0 update, a few things broke. I took the opportunity to rewrite everything from Python to JavaScript and support Factorio 2.0 and the Space Age DLC. It's now also possible to easily modify the style of the drawings. Let me know if you find any bugs or if you have ideas for features.
