Primary Grid Compositions

Broadway Boogie Woogie

Colored squares pulse along yellow grid avenues like NYC traffic; intersection dots blink in red, blue, and yellow referencing neoplastic's 1943 painting.

When to use it

Art-themed hero backgrounds, neoplastic/De Stijl style pages, ambient generative art displays.

When not to

Contexts needing legible text overlays — the animated grid creates visual noise. Background color is hardcoded off-white.

Working with an AI agent

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

Change grid spacing from gap=30 to gap=40, increase band width from band=11 to band=16, and swap yellow road color to white for a classic black-grid look. 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

  • grid spacing (gap=30)
  • band width (band=11)
  • runner speed range (rand(.04,.11))
  • blink density threshold (Math.random()<.18)
  • color palette (PAL array)
  • blink square size (sz=13)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

  • IIFE wrapper
  • prefers-reduced-motion guard (REDUCED)
  • visibilitychange pause/start
  • DPR-aware fitCanvas()
  • theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)

Known limitations

  • Background color hardcoded in CSS (#f7f4ec) — must edit both CSS and C.white constant to change
  • Runner/blink layout re-randomizes on each resize

  • The Rebalancing Gridneoplastic grid of black lines slides to new layouts while red, blue, and yellow cells fade in, resolving into a balanced composition every few seconds.
  • Self-Assembling Compositionneoplastic grid builds itself every 4 s: cells scale in staggered, black lines draw outward, primary colors fill random regions, then recomposes anew.
  • Trading WeightRed and blue blocks trade mass across a fixed axis; a yellow counterweight keeps the neoplastic grid balanced. Slow eased transitions reseed randomly.
  • Self-Painting CellsA fixed asymmetric neoplastic grid whose cells autonomously cycle through red, blue, and yellow with smooth CSS transitions, like an unattended painter at…
  • Victory Boogie MarqueeA 9x9 neoplastic grid rotated 45° as a diamond; red, blue, and yellow squares ripple diagonally in a boogie-woogie march via time-stepped index.
  • 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.
