I have been seeing these blurred backgrounds all over the place, so I would like to know the exact steps how to reproduce something like this http://dribbble.com/shots/918102-Some-icons?list=popular&offset=341. What I can imagine, is that they first blurred an image/gradient with a gaussian blur. But there has to be something more to it, right ?

+) How do I correctly use a gradient instead of a picture?
