Noise Grain adds an organic texture layer over any background. At 3% opacity it’s imperceptible but makes the site feel alive — exactly what you see on this page. At higher opacities it creates a film grain aesthetic that pairs beautifully with dark UI.
Three rendering modes: lightweight CSS SVG filter (no JS), Canvas pixel manipulation, and WebGL shader (highest performance at full screen).
