Noisy is a jQuery plugin that adds random noise to a given element.
$('body').noisy({
noiseParticles: 0.9,
tileSize: 200,
backgroundColor: '#EDEBDE',
maxNoiseOpacity: 0.078,
fallbackImage: 'fallback.png',
monochromatic: false
});
But since all parameters are optional you can just use it like this: $('body').noisy();
