I haven't spent much time tweaking my PC at work. My personal touches did not go far beyond choosing a wallpaper image from the options provided by Windows - this rather Maine-ish lighthouse.
My Dad sent the image on the right - taken today on my parents' walking holiday in the Lake District. It made me a little homesick for a moment for that kind of landscape.
Not that the landscape round here is bad at all - as I remembered when I looked back at the other screen!
