Laser field

Pointer-reactive laser beams in a WebGL shader with three layouts: a fan from the floor, a vanishing-point grid and a prism that splits one beam into a spectrum.

What it is for

Behind a hero or event page (first child of a position:relative section; fills its parent).

Accessibility

  • Keyboard. Components in the kit are written to be reached and used with the keyboard. Try it: press Tab inside the preview.
  • Reduced motion. With prefers-reduced-motion on, animation settles to its finished state at once.
  • Touch. Pointer-follow effects are skipped on touch screens; controls stay finger-sized.
