Cursor & Pointer

Elastic Ring

Glowing pink ring trails the pointer with damped-spring physics, stretching along velocity and squashing across it. Auto-demos on a Lissajous path until first deliberate input.

When to use it

Creative portfolio heroes, cursor-replacement effects, interactive showcases where pointer physics add tactile feel.

When not to

Utility UIs where a hidden cursor frustrates users. Touch-only devices where pointermove never fires.

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 = '#ff5ca8')
  • ring base size (Math.min(W,H)*0.085)
  • spring stiffness (ax=(tx-rx)*0.14)
  • damping factor ((vx+ax)*0.80)
  • Lissajous radius scale (R*0.30)
  • theme tokens (:root dark defaults + [data-theme=light] overrides)

Keep intact

  • DPR-aware canvas sizing and setTransform
  • visibilitychange pause guard
  • prefers-reduced-motion static fallback render
  • 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

  • Cursor is hidden (cursor:none) — must restore for production if replacing only part of a page
  • 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.
