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 when idle.

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:

Change ACC to '#00eaff', increase base ring size from Math.min(W,H)*0.085 to 0.12, and slow the spring by changing the acceleration factor from 0.14 to 0.08. 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 = '#ff5ca8')
  • ring base size (Math.min(W,H)*0.085)
  • spring stiffness (ax=(tx-rx)*0.14)
  • damping factor ((vx+ax)*0.80)
  • idle timeout before demo resumes (2600ms)
  • 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)

Known limitations

  • Cursor is hidden (cursor:none) — must restore for production if replacing only part of a page
  • No touch fallback — demo auto-plays but ring never tracks finger on touch devices
