# Kay Facher

> The personal website of Kay Facher, Lucerne, Switzerland: a living, real-time model of Lake Lucerne in WebGPU, tonight's sky, every satellite overhead, a dragon text adventure, Föhn (a paraglider in today's real wind, or a jet down the whole lake), a homelab whose lights are this page's own requests, and an AI twin. A personal site: it offers no services, and nothing here concerns paid work.

Name: Kay Facher. Website: https://facher.ch.
Home: Lucerne (Luzern), Central Switzerland, Switzerland, on Lake Lucerne (Vierwaldstättersee). On the horizon: Pilatus, Rigi, Bürgenstock, Stanserhorn.
Work: "Works in IT". That is the whole of it on this site.
Contact: hello@facher.ch, the contact form at the bottom of the page, or a lantern in the guestbook. Code: https://github.com/kayfacher.

How I sound, in my own words:
- "I work in IT, I live by the lake, and I build strange things for the web."
- "Happiest in a tent, on a horse, or lost in a book about somewhere that doesn't exist."
- "I like systems that just work — and websites that shouldn't be possible."

Interests:
- Outdoors: Camping and being outside — the further from a power socket, the better. Pilatus and Rigi are the view from home.
- Horse riding.
- Books: Fantasy and science fiction — the books that made me want to build worlds.
- Music: Music is always on somewhere.
- Games: Games — playing them, and building small ones.
- Homelab: A homelab: the place where IT stops being work and starts being play.

Questions I've answered before:
Q: Where are you based?
A: Lucerne, in central Switzerland — right by the lake, with Pilatus out the window.
Q: What do you do?
A: I work in IT. This site is the personal side: the things I'm into and the things I build for fun.
Q: Can I hire you?
A: No — this is a personal site, and I keep work out of it. But I'm always happy to hear from people — say hi.
Q: How did you build this site?
A: From scratch: Next.js, a custom WebGPU engine running in a worker, real elevation, weather, sky and satellite data, and a lot of late nights. The colophon has every detail.
Q: How do I reach you?
A: hello@facher.ch, the contact form at the bottom of the page — or leave a lantern on the lake.

## The page

- [top](https://facher.ch/en): Arrival: my name in GPU particles, a split-flap greeting in 12 languages, a Swiss station clock, a free/busy dot.
- [here](https://facher.ch/en#here): A real-time 3D Lake Lucerne: real terrain, live weather and wind, lake temperature, today's steamers, and a 20,000-year deep-time dial: the ice age glacier, the lake's birth, the forest, the first farmers and the town growing, each age toured by the camera.
- [out-there](https://facher.ch/en#out-there): Camping and riding: tonight's real star sky over Lucerne, a campfire in a ring of stones, a horse grazing beside it, and the Milky Way where it really is tonight.
- [worlds](https://facher.ch/en#worlds): Fantasy and sci-fi: a bookshelf, the live ISS and every satellite in orbit, and Pilatus, a text adventure about the Lucerne dragon.
- [sound](https://facher.ch/en#sound): A generative score that follows Lucerne's weather and sun, with a playable synth and WebMIDI.
- [play](https://facher.ch/en#play): Föhn: a paraglider game flown in today's real wind, with live ghosts and a daily leaderboard — or, in its jet mode (ADHD mode), a jet at 830 km/h (1,300 on the afterburner) down the whole lake from Lucerne to Flüelen through ten rings, with its own board.
- [machine](https://facher.ch/en#machine): Tech and homelab: this request's path through Vercel, live Web Vitals, the build, and a 12U homelab whose sockets light up with this page's own requests.
- [signal](https://facher.ch/en#signal): Contact, a lantern guestbook, who's here right now, and a poster of your visit.

## For agents

- [MCP server](https://facher.ch/mcp): stateless Streamable HTTP, read-only tools: about_kay, interests, lucerne_now (live weather, lake, steamers, sky), kay_status (free/busy only), site_map.
- WebMCP: in supporting browsers, the page registers its own tools (navigate, set_weather, set_time, set_theme, toggle, run_terminal, play_melody, lucerne_now, kay_status) with navigator.modelContext.
- [Ask the AI twin](https://facher.ch/en?ask=What%27s%20the%20lake%20like%20right%20now%3F): any page URL with ?ask=<question> opens the twin with that question.
- [Live data](https://facher.ch/api/now): JSON with Lucerne's current weather, wind field, lake temperature and steamers.
