De Stijl Neoplastic

Dynamic Equilibrium

Six neoplastic-colored rectangles hang from a tilting beam; a spring-damper drives it toward equilibrium while a slow bias keeps it gently alive.

When to use it

Art/design portfolio heroes, screensaver-style ambient displays, dark-background contexts needing calm physics-driven motion with a neoplastic aesthetic.

When not to

Light-background layouts (background hardcoded near-black). Contexts where ambient motion competes with adjacent readable content.

Working with an AI agent

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

Change the bias retarget range from 0.16 to 0.30 and shorten the interval (biasT=1.2+Math.random()*1.2) for more restless swinging. 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

  • block colors (RED/BLUE/YEL/PAINT constants)
  • block weights and offsets (blocks array w/off fields)
  • spring stiffness and damping (k=14, c=4.6)
  • bias magnitude (0.16) and retarget interval (2.4s)
  • beam length fraction (S*0.78)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

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

Known limitations

  • Background hardcoded to near-black (#0e0e10) — edit CSS and draw() fill to change
  • Reduced-motion mode renders a single static frame with no animation

  • Grid RecomposeBlack grid lines slide between asymmetric positions with cubic easing, repartitioning red, blue, yellow, and off-white rectangles in neoplastic style.
  • Boogie Pulse26 primary-color blocks travel and blink along a black asymmetric De Stijl grid over static color-field plaques, evoking neoplastic's Broadway Boogie-Woogie.
  • Block FillPrimary-color rectangles wipe and rise in staggered sequence to fill cells of an asymmetric black De Stijl grid on warm white; loops continuously.
  • Line WeaveHorizontal and vertical cream lines thread and interlace over primary-color blocks on a dark field, with bright nodes at crossing points during the weave…
  • Counter CompositionA neoplastic grid of red, blue, and yellow cells divided by black bars rotates from 38° and settles to a gentle 15° resting angle with a slow living drift.
  • Split PlaneA square canvas splits along alternating seams; two halves slide apart and reflow into new De Stijl primary-color compositions every 4.4 s.
