Real-time 3D / AI — 2026
A small shared 3D world where you talk with your people and an AI builds what you describe.

Personal project
What I did
- Say “Luna, set up a planning corner” and the built-in assistant builds it from a catalog of 70+ low-poly models, writes the plan on a whiteboard and replies with an undo link.
- Walk around together in third or first person with real physics, see each other as avatars and talk with spatial voice.
- Build by hand with a library of models, shapes, notes, floor paint and collaborative Excalidraw boards that everyone edits live.
- Every change is saved as a version you can preview and restore; the layout also works on phones with touch controls.
