If you have a firmware 5 kindle (Touch, Paperwhite, Voyage, Oasis), see the screensavers hack thread on Mobileread:

> Dou you prefer to just show the last thing that was on screen, with an overlay indicating when the device's alseep? Just drop a blank file named last in the linkss folder. Restart your Kindle ([HOME] -> [MENU] > Settings -> [MENU] > Restart; or simply use the Screen Savers > Restart framework now button in KUAL), and you're done

Obviously make sure you read everything (really, everything, including all the tiny text, even if it doesn't seem relevant) before you start.
