When to use it
Memphis/retro-themed hero sections, loading screens, or decorative panels needing bold ambient motion without user interaction.
When not to
Contexts requiring text legibility over the canvas or low-end devices where glow sprites may stress GPU compositing.
Working with an AI agent
Every component ships agent-ready metadata. An example instruction for this one:
Change the totem's wobble speed by setting the frequency multiplier from 1.15 to 0.7 in drawFrame, and swap COL.orange to '#00eaff' for a cooler palette. 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
- color palette (COL object)
- wobble frequency (1.15 multiplier)
- layer definitions (L array — shape types, sizes, phases)
- glow intensity (GLOW=14)
- gap between layers (gap=0.08)
- squiggle color and size (COL.yellow, sw=unit*0.85)
- theme tokens (:root dark defaults + [data-theme=light] overrides)
Keep intact
- offscreen sprite baking pattern (buildSprites — critical for perf)
- visibilitychange pause/resume
- prefers-reduced-motion single-frame fallback
- IIFE wrapper
- theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)
Known limitations
- Glow is baked into offscreen sprites at resize — changing GLOW at runtime requires a resize trigger to rebuild
- Terrazzo speckle is 6 hardcoded dots via CSS radial-gradient, not truly random
