Replica documentation

The Wisdom and/or Madness of Crowds

Local route /interactive-explanation/crowds/ vendors the original chapter-based slideshow, network simulation engine, and media assets with only local metadata fixes, translation cleanup, and the shared public reference footer layered on top.

Source snapshot

Vendor baseline came from the published ncase/crowds site tree. The local copy keeps the chapter-based slideshow HTML, simulation scripts, audio library, and sprites, while replacing the old supporter-facing route with a neutral local stub.

  • Live page verified against https://ncase.me/crowds/ on 2026-03-10.
  • CC0 provenance stays documented here while the public route exposes only the shared reference footer.
  • Translation listings, alternate links, and supporter affordances were pared back locally so the shipped route does not advertise missing or external pages.

Asset and source map

  • crowds/index.html preserves the slideshow shell, hidden words/reference content, and navigation markup.
  • crowds/js/chapters/ maps each chapter to its simulation and pacing logic.
  • crowds/js/sim/ contains peeps, connections, cutting tools, and the simulation engine.
  • crowds/js/slideshow/ controls navigation, modal behavior, audio preloading, and sandbox UI.
  • crowds/audio/, crowds/social/, and crowds/sprites/ stay vendored as source assets, while crowds/supporters/ now serves a neutral local stub.

Known deviations

  • The public route now uses the shared footer instead of any in-page provenance or creator callouts.
  • The credits chapter was trimmed so it keeps music attribution and further reading while dropping repo/supporter promo.
  • rel="alternate" links, translation-guide comments, and upstream translation callouts were removed from the public entry HTML.
  • In-body links to Trust and Polygons now point to the local replica routes, and the supporters modal path was removed from js/slideshow/Modal.js.

Reproduction notes

  • Keep the chapter scripts and hidden words/reference blocks together; they form one tightly coupled runtime.
  • Preserve the audio and sprite paths exactly, because the preloader hard-codes them throughout the slideshow.
  • Audit credits, translations, and modal routes separately from the chapter flow, then run node interactive-explanation/tools/check-public-surface.mjs.
