Grain Flicker: A grain layer that redraws itself every few frames, so flat backgrounds get the restless flicker of a running projector instead of a fixed texture.

## Frameworks

react, vue, svelte, astro, html

## Preview controls

These controls are passed to the demo. Defaults and limits describe the preview; consult the implementation for its full prop API.

| opacity | number | 0.06 | From 0.02 to 0.25; step 0.01 |
| grainScale | number | 1 | From 1 to 4; step 1 |
| refreshInterval | number | 2 | From 1 to 12; step 1 |
| animate | boolean | true | No additional limit in the metadata. |
