Cursor & Pointer

Ripple Field

Grid of dots ripples outward in expanding pink rings as the pointer moves; dots displace radially along each wavefront. Lissajous auto-demo when idle.

When to use it

Dark-mode hero backgrounds, interactive landing sections, ambient pointer-reactive displays where motion follows the cursor.

When not to

Low-end devices — per-frame dot displacement loop scales with grid size. Light backgrounds require CSS overrides; avoid where subtle motion is needed.

Working with an AI agent

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

Change the accent color from pink to electric cyan by setting ACC=[0,234,255], and increase ring expansion speed by changing the ringSpeed multiplier from 0.62 to 0.85. 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

  • accent color (ACC=[255,92,168])
  • dot base radius (R=2.2)
  • grid gap (gap=Math.max(14,...))
  • ripple ring speed (ringSpeed multiplier 0.62)
  • max simultaneous ripples (MAXR=8)
  • auto-fire interval (interval=real?0.34:0.62)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

  • DPR-aware canvas sizing and setTransform
  • IIFE wrapper
  • visibilitychange pause guard
  • reduced-motion static fallback (fire + pre-step loop)
  • theme hook (?theme= bootstrap + forever:theme message listener + theme tokens)

Known limitations

  • Per-frame dot displacement is O(dots * ripples) — heavy on large viewports with many ripples active
  • Background color hardcoded in CSS (#0a0a0f) — must edit to change from dark navy
  • No aria semantics — purely decorative canvas
