Lucerne · Switzerland
KayFacher.
I work in IT, live by the lake, and build strange things for the web.
Get the highlights.
Lake Lucerne, from real elevation data.
Here.
The sun, moon, clouds, wind and rain bring Lucerne's latest available conditions to this lake. Touch the water and watch ripples spread across its surface.

Out there.
When I'm not at a screen I'm in a tent or on a horse. This is tonight's sky over Lucerne — every star, planet and satellite where it actually is.

Fantasy & science fiction.
Other worlds.
Books about places that don't exist are the reason I build things. Here's the shelf — and a story you can play, built on Lucerne's own dragon legends.

A text adventure
Pilatus.
In 1421 a dragon flew over Lucerne and dropped a stone. Pontius Pilate's ghost haunts a lake on the mountain. You have a lantern and a bad feeling.
A score that never repeats.
Sound.
Music is always on somewhere. Turn it on here: the score is generated live from Lucerne's weather, the time of day and where you are on this page. Plug in a MIDI keyboard and play along.
Or play with your keyboard: A S D F G H J K
Föhn — paraglide over Pilatus or fly a jet down the lake.
Play.
A paraglider game on the real mountain, in the real wind blowing over the lake today. Thermals bubble off the slopes the sun is actually shining on. Race the ghost of today's best flight. Or take the jet down the whole lake to Flüelen. Gamepad supported.
Launch at Pilatus Kulm, fly through four rings — Fräkmüntegg, Sonnenberg, Horw, the Kapellbrücke — and land on the Ufschötti meadow.

Say hi.
Signal.
