1. If you have the ad-supported one, ads.
   
2. If you paid the extra $20 (or had Customer service remove them for free -- they do that for non-US customers) then as HarryT said, just random images -- stuff like rolled-up newsprint, typwriters, pencils, those baby blocks with the letters, etc.
   
   Or you can use the Screensavers hack:
   

   What Does It Do?:

   
   This will allow you to customize the screensavers (or sleep screens) used by your Kindle, replacing them either with your choice of images, the cover of the last book you opened or a simple unobtrusive overlay .
