The place
The scene is an imagined stretch of the Spree's forest. Below Cottbus, the real river frays into the Spreewald, an inland delta of hundreds of quiet channels threading through alder woods, a UNESCO biosphere where mail is still delivered by poled barge. Our name folds that river into the work: co for company, Spree for the water.
The arch is inspired by the Rakotzbrücke in Kromlau, a basalt garden folly commissioned around 1860 by Friedrich Hermann Rötschke, designed so that its reflection completes a perfect circle in still water. It stands in Upper Lusatia, not in the Spreewald itself; we borrowed it across the map because the metaphor was too good to leave behind. Crossing it is forbidden: it was built to be seen, and its work happens on the water. "Devil's bridges" carry a much older story: the devil builds the impossible arch and demands the first soul to cross, and the builder sends a dog ahead. The legend is a legend; we tell it as one.
On this site the arch is raised the way real arches are raised: on timber centring, stone by stone, keystone last. Then the centring comes down. That is also how the practice works, and it is the only sentence of this page that is secretly about you.
The craft
Everything you see is drawn, not downloaded. The world is built at runtime from procedural geometry and canvas-painted textures: the arch is 28 voussoirs and a keystone on a semicircle, the alder carr is instanced brush-stroke billboards, the reeds, mist and treelines are painted in code at boot. The water carries a real planar reflection, disturbed by a GPU wave simulation that lives in world space: your cursor, the stag's muzzle and the dragonflies all write real ripples into the same field, which is why they foreshorten correctly wherever the camera stands. One composite pass adds the paper: tinted shadows, pigment-pooled edges, fiber grain.
The one guest is the stag, a CC0 rigged model by Quaternius, re-shaded to sit inside the painting; his idling, drinking and glances are real skeletal animation. Type is Fraunces and Inter. Built with Astro, three.js and Lenis; prerendered HTML, almost no JavaScript on the Journal pages.
