The Seventeenth Stone
A forgotten practical beginning, a village custom, and two timelines that get precisely the same weather.
Open the interactive exhibit ↗Operate the model
Use the number seed and copying-pressure controls, advance the village through years, and fork a second village. Remove a stone, reveal the ordinary origin, or demonstrate that stone count does not affect the spring. The controlled comparison shares rain and random draws by design; the stories and social updates then diverge according to coded rules.
What the model actually is
Twenty-four fictional goblins, social-learning tendencies, and simple narrative memory are represented by a self-contained deterministic JavaScript simulation. The spring's flow is independent of the decorative stones by declaration in the code. This is a visualization of hypotheses about traditions, not an investigation of actual people or trained LLM agents.
Limits and checks
The original HTML runs without external assets or APIs. An injected-document Chromium smoke test exercised the year controls, intervention fork and notebook, and reported no page errors or outgoing requests. Direct file navigation, live deployment behavior, and other browsers/devices were not certified by this test.
