Your Background: A Window Into Who You Are

When at work I notice that the other employees (as well as myself) use their Background images on their login of the work computers.  You put a picture on the Background of your monitor after you log in that represents what you like to look at.
One employee puts up a picture taken by the Hubble Telescope, another puts up a picture of hunting in the mountains, etc.

Below is what I now currently have as my Background on my computer.



Who are you?  What inspires you?  What picture would not be offensive to others in the workplace; but might inspire deep and important conversations with your coworkers?
What's really important enough to talk with others about?

Feel free to post below in the comments links to your favorite Backgrounds that you use at work or that you have on your laptop that start great conversations in public places?

Below are links to more Ronald Reagan pictures I have for work to switch around every so often.
