A way to create random-noise background image (png) with javascript?

Question

The new layout of YouTube added a background random-noise which I like very much, having seen almost exactely the same effect on other sites, so I plan to use the same technique

There are two jQuery plugin libraries that do exactly what you are looking for: NoiseGen and Noisy. Haven't used either yet but they both look pretty good.
