Silly request (or is it?). I like to keep my pc distraction free but I also love interesting backgrounds. When focusing on the app I prefer not to be distracted by a detailed background so I took a nice background and blurred it a bit. You can download the original and blurry version. I'm very very happy with the result, so I was wondering if there is a tool that uses the gpu to blur the background when the desktop is not active, but fades the background into focus when there is no windows in the way. Too much for autohotkey I'm afraid so I can't do it. Apparently the effect on the windows theme is called Aero Blur.
Would make a nice NANY app or donationware tool?
