DIY: Cow skin pattern for your GIMPed cows

I wanted to share with you a (very simple and short) method for creating cow-skin patterns, totally random each time, for your GIMPin needs.
This can actually work the exact same way in GIMP, PS or Paint.NET.

I will demonstrate with GIMP, but it is so simple you can do it in any of the aforementioned programs.

So here goes:

1. render some clouds

You may want to smooth it a bit maybe if you get a grainy clouds render.

2. set levels

Black level and white level to 127.

3. and there you go - cow skin:
Now you can cut it up to fit your cow...
