Primary Grid Compositions

Self-Assembling Composition

neoplastic grid builds itself every 4 s: cells scale in staggered, black lines draw outward, primary colors fill random regions, then recomposes anew.

When to use it

Art/design hero backgrounds, generative art showcases, or any ambient abstract motion context with a geometric aesthetic.

When not to

Contexts needing a stable background — the full canvas clears and redraws every few seconds, which is disruptive behind content.

Working with an AI agent

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

Change the recompose interval to 6000ms (replace 4200 in setTimeout), reduce colored cell count by changing the colorCount floor from 3 to 2, and swap C.red to '#e85d04' for a burnt-orange 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

  • recompose interval (4200ms in setTimeout)
  • subdivision depth (depth=4 in subdivide call)
  • color palette (C object — white/black/red/blue/yellow)
  • colored cell count range (3 + Math.random()*3)
  • stagger delay per cell (i*45 ms)
  • border/line thickness (TH=7)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

  • IIFE wrapper
  • prefers-reduced-motion guard (REDUCED)
  • visibilitychange stop/start logic
  • double-rAF flush for CSS transition trigger
  • theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)

Known limitations

  • Canvas clears entirely on each recompose — no smooth morph between states
  • Line rendering uses absolute-positioned divs; very narrow cells can produce overlapping lines
  • No aria live region — screen readers only get the static aria-label

  • Broadway Boogie WoogieColored squares pulse along yellow grid avenues like NYC traffic; intersection dots blink in red, blue, and yellow referencing neoplastic's 1943 painting.
  • Trading WeightRed and blue blocks trade mass across a fixed axis; a yellow counterweight keeps the neoplastic grid balanced. Slow eased transitions reseed randomly.

  • Equilibrium Engineneoplastic grid with spring-driven lines; primary color blocks recolor every 2s; a center-of-mass dot tracks the weighted area of colored cells.
