I build living, self-organizing things
How order arises from traces, not consensus, is the one question behind everything I make — across code, art, and theory.

On the App Store
Free, no accounts, no tracking — the same engines as the repos below, native.
— the slime-mold simulation as an ambient display for iPhone, iPad and Apple TV.
— the I-Ching oracle for iPhone, iPad and Apple Watch.
Generative art & music
- Physarum — multi-species slime-mold simulation in WebGPU. Slime mold is the textbook case of stigmergy: agents coordinating through the traces they leave, with no central plan. The aesthetic is the idea. Background
- kuro-screensaver — standalone retro-CRT 3D screensaver, five seeded procedural scenes. Background
- synthwave-surfer — deterministic generative synthwave: pick a genre engine and a seed, get a full arrangement. Background
3D / Gaussian splats
- Autosplat — video → interactive 3D Gaussian splat, automated and local on Apple Silicon; ships with a static viewer PWA to orbit or walk through the result. Background
Obsidian plugins
Local-first tools for the notes app I live in — nothing leaves your machine.
- json-editor — view and edit JSON files with a Tree/Source toggle. Background
- vault-rag — offline retrieval over your vault: related notes, semantic search, grounded chat with a local LLM. Background
- vault-crews — run autonomous local LLM agent teams on your vault via LM Studio. Background
- slide-deck — turn a Markdown note into a slide deck, export to PDF or PNG series, with live readability checks.
- letterhead — business letters (DIN 5008 or modern) from note frontmatter, exported to PDF via the print dialog. Works on desktop and iPhone. Background
- paperize — export the active note as a clean, text-selectable vector PDF. Desktop, iPhone and iPad.
- image-to-markdown — transcribe a note's images to Markdown with a local vision LLM, non-destructively. Background
- yijing-oracle — cast the I Ching in your vault: three-coin oracle with Wilhelm hexagram texts, readings saved as notes.
- kuro — Neo-Gothic, Post-Cyberpunk, CRT-Phosphor theme: Twelve Signals palette, four Aspects. Background
Local-first tools & apps
- podcast-to-youtube — podcast audio → YouTube video, automated and local. Background
- Yijing — I-Ching oracle with optional AI interpretation via a local LLM. Static site, plus native apps. Background
- NeuroVIM — learn Vim disguised as a cyberpunk spy thriller; an AI handler hands you missions. One codebase, two ways to play: as a web app and desktop build, or inside your vault. Background
Everything is built to run on your machine, not someone's cloud. Open source, AGPL — traces contributed to the commons should stay in the commons.
I'm a neurodivergent maker, and I work the way that fits: externalizing thought into traces rather than holding it all in my head — which, fittingly, is the same principle again.
