Theme 1 · 11 projects

Computational Chemistry

This theme collects transparent implementations of computational chemistry methods. The projects are meant to make difficult ideas inspectable: powerful enough to run meaningful examples, but modular enough to take apart and study piece by piece.

Theme 2 · 8 projects

Scientific Visualization

This theme turns scientific data into structures people can inspect and build with. The emphasis is practical understanding: visual tools for exploring molecules, constructing surfaces, converting grids into geometry, and sharing models in a clearer form.

Theme 3 · 26 projects

Retro Computing

This theme is about keeping older machines alive and using them as readable foundations for modern computing. Vintage systems expose memory, buses, storage, video, and firmware in ways that make the ideas behind today's computers easier to understand.

Theme 4 · 7 projects

Open Education

The educational projects are written for people who want a gentle entry point before the mathematics or code becomes demanding.

Theme 5 · 12 projects

Homebrew Hardware

These projects sit at the bench: PCBs, firmware, microcontrollers, buses, ROMs, and the pleasant discipline of making electrons behave.

Languages and Tools

Sometimes the project is not the thing made with a tool, but the tool itself: a small language, a tiny CPU model, or a helpful command-line utility.
