Changing Fonts In Ubuntu

Have you ever tried changing the fonts of your ubuntu system?
You can easily give your system a different look and feel by merely changing the fonts.
There is no new installation required.Just go to the "Appearance" section and click on the "Fonts" tab.Here you can start playing around with fonts.Just take a screenshot of the window before altering any settings so that if you wish to return to the default settings,you have an easy reference to do so.Use bold italic fonts for the look that you see in the screenshot.
May be it was too simple to try!
