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 until first deliberate input.

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:

Adjust the existing palette tokens and effect parameters while preserving manual control. Arrow keys steer; first click/touch stops the attract path permanently for this mount. Keep demo-v1 lifecycle marker, __foreverPreview.demoEnabled initialization and forever:interactive handler. Preserve reduced motion, visibility suspension and theme switching.

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)
  • sticky demo-v1 preview lifecycle; stop attract work, retain manual feedback and settling
  • pointer/touch takeover, keyboard access and visibility suspension
  • demo-v1 preview lifecycle: initialize demoEnabled from window.__foreverPreview and stop attract work on the window forever:interactive event; retain manual feedback, settling, cleanup and explicit sessions

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
  • Control state is local to each mount; format changes preserve preview takeover but create a fresh source instance.
  • State remains local to each mounted instance; format/theme remount preserves takeover, not component values.
