The seven objects in this cabinet are projects with an open public repository. Every row carries the real repository path and the system’s real figures.
- 03
The orbital simulation that fronts this portfolio is hand-built in WebGL, with GPU-baked terrain, worker-pooled generation and automatic quality tiers. It is the heaviest object in this catalogue and its own proof.

Orbit is the catalogued orbital radius, mass is the object’s size and sat is the satellite count. All three come from universe.json — the same numbers the simulation uses to draw this system.

The navigable version of this same portfolio runs as a real-time orbital simulation: each galaxy is an area of life, each planet a project, each satellite a link. It is hand-built in WebGL, with GPU-baked terrain, worker-pooled generation and automatic quality tiers — the heaviest object in this catalogue and its own proof.
