Noise

Animated film grain / noise overlay adding subtle texture and motion.

Default

The overlay is an absolutely positioned canvas, so put it inside a relatively positioned parent. Every prop is wired to the controls underneath.

Ooh, edgy!

Prop	Type	Default	Description
`patternSize`	`number`	`250`	Defines the size of the grain pattern.
`patternScaleX`	`number`	`1`	Scaling factor for the X-axis of the grain pattern.
`patternScaleY`	`number`	`1`	Scaling factor for the Y-axis of the grain pattern.
`patternRefreshInterval`	`number`	`2`	Number of frames before the grain pattern refreshes.
`patternAlpha`	`number`	`15`	Opacity of the grain pattern (0-255).

Keyboard shortcuts and ARIA behavior.

The canvas ignores pointer events, so it never blocks the content underneath.
Raise patternRefreshInterval to slow the flicker for users who prefer reduced motion.
