Noise and Clouds

Im looking into noise and clouds, take a peek at my thread on /3/ for pics
http://boards.4chan.org/3/res/230412#230469

By 'programmers noise' i mean

for (var y : int = 0; y < texture.height; ++y) {
    for (var x : int = 0; x < texture.width; ++x) {
        var temp : float = Random.value;
        var color = Color(temp,temp,temp);
        texture.SetPixel (x, y, color);
    }
}

Be cool if someone could explain the photoshop filters

*** English interpretation failed.

What you are looking for is Perlin noise: http://en.wikipedia.org/wiki/Perlin_noise

Reading the title, I thought this was a cloudsourced startup selling a noise datastream through a freemium API.
I was disappointed for a moment, then I applied to Y combinator.
