Particles & Physics

Charged Plasma Lattice

Charged particles attract/repel via Coulomb forces; teal bonds crystallize between opposite charges as temperature pulses between order and chaos.

When to use it

Dark-mode hero backgrounds, science/tech themes, ambient visualizations where dynamic structure formation adds interest.

When not to

Low-end devices — O(N²) force loop is CPU-heavy. Light backgrounds (hardcoded dark). Contexts needing legible text overlaid.

Working with an AI agent

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

Change positive charge color from '#C0B459' to '#ffaa00' and negative from '#1DACC9' to '#00ffaa', then cap particle count to 40 by editing Math.min(64,...). 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

  • particle count range (Math.min(64, Math.max(34, ...)))
  • charge colors (POS='#C0B459', NEG='#1DACC9')
  • bond color ('rgba(29,172,201,...)')
  • temperature pulse speed (t*0.55)
  • pointer charge strength (9000)
  • Coulomb force strength (1400)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

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

Known limitations

  • O(N²) force calculation — CPU-bound on low-end devices at N=64
  • Reduced-motion shows only a static snapshot, no fallback animation
  • Background color hardcoded in CSS (#0b0014)

  • Gravity Dot RainMulticolored dots fall under gravity with motion trails, bounce off the floor, and scatter away from the cursor on a dark navy canvas.
  • Firework BurstColorful glowing sparks burst radially, fall under gravity, and fade against a dark sky. Auto-launches bursts; click anywhere to add more.
  • Confetti CannonColored rectangles fire from bottom corners in auto-cycling bursts, tumbling with gravity and flip animation. Click anywhere to trigger a cursor burst.
  • Bouncing Balls7–14 glossy pastel balls bounce off walls and collide with elastic physics; cursor repels balls within a 70px radius.
  • Spring ChainA 16-node spring chain whips and follows the cursor in a lime-to-gold gradient; drifts in a figure-eight pattern when idle.
  • Cloth Wave GridAn 11x11 wireframe grid ripples like cloth via sine/cosine waves in cyan-to-violet hues; mesh nodes bulge away from the cursor on hover.
