A simple jQuery plugin which generates a noise effect on the background of DOM elements using HTML5 canvas element.

Inspired from Jeffrey Way's tutorial:
http://net.tutsplus.com/tutorials/javascript-ajax/how-to-generate-noise-with-canvas/

AVAILABLE OPTIONS:
opacity : Opacity value of noise image. Between 0.02 - 0.20 is enough. (Default: .08)
size: Canvas size in pixels. Higher values degrades performance. Between 40-80 is enough. (Default:40)
color: Fallback background fill color if browser doesn't support canvas. (Default: '#ebebeb')

USAGE:
$('body').bgnoise();
$('body').bgnoise({ opacity:0.1, size:50})
$('body').bgnoise({ opacity:0.1, size:50, color:'orange'})
