If you haven't been there recently, you can now add a background to your home page. It doesn't seem like such a big deal until you realize that the background reflects the world outside your window.
All you have to do is tell it where you are. It's kind of nifty and only take a minute or two to set up. It may be especially helpful for anyone who sits in a cubefarm and can lose track of time.
Just select the theme you would like, and then you will be asked to provide your location. Two clicks and your done.
