Well, as you can see the template has been changed. I got tired of the blah black blackness of the "minima" template. This one is called rounders.
People who see my computers often know that I change my wallpaper frequently. At home the motif is generally paintings of nudes/semi-nudes. At work it is usually some large scale nature/technology view like an aerial view of a bridge or a spacecraft in space, or paintings by some well known painters like Matisse, Cezanne, or Bouguereau.
Here is my current home wallpaper:
Oh, and that profile pic is an old one, like 1985 or so!
