When to use it

Japanese-themed hero backgrounds, cultural art exhibits, ambient screensavers, or any dark-mode layout wanting serene generative motion.

When not to

Light-background UIs (background hardcoded dark navy). Contexts where legible text overlays are needed over the animated area.

Working with an AI agent

Every component ships agent-ready metadata. An example instruction for this one:

Change crane count to 10 by setting N=10, shift the sun color to gold by replacing CORAL with '#e0c040' in the sun arc fillStyle, and slow wing flap by changing t*7 to t*4 in the frame loop. Theme: dark tokens live in :root, the light variant in :root[data-theme="light"]; ?theme=light or a {type:'forever:theme'} postMessage switches at runtime.

Safe to edit

  • crane count (N=7)
  • flight speed range (sp[i] = 0.018 + random*0.03)
  • band colors (INDIGO1, INDIGO2, TEAL, CREAM)
  • sun position and size (W*0.26, H*0.18, min*0.11)
  • wing flap rate (t*7)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

  • DPR-aware canvas sizing and ctx.setTransform
  • visibilitychange pause/start guard
  • prefers-reduced-motion static fallback branch
  • IIFE wrapper
  • theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)

Known limitations

  • Background color hardcoded in CSS (#0f1822) — must edit to change dark background
  • Crane x-position wraps via modulo but t0 resets on resume, causing slight position jump after tab hide/show
