Read the full case study

Tau Ceti IV is a 3D surface-data explorer for the three maps in Bungie's Marathon. It's an independent fan project rather than client work, built over three days with Claude Code, and the role covered the design, the engineering and the soundtrack.

  • Built the explorer in three.js and React Three Fiber, drawing each map's line geometry as one set of segments with a height-graded shader.
  • Rebuilt the interface in Marathon's visual language, from the palette and type to the field-tag markers and HUD.
  • Shipped a live contacts layer where runner crews and UESC patrols walk, fight, fall and extract, driven by a unit-tested simulation core.
