Light My Kindle

When you put your Kindle in sleep mode, a screensaver appears that can be anything from a Kindle tip or a picture of a classic author. Some Kindle users figured out how to add your own pictures to use as screensavers. The process is explained in great detail here and seems fairly simple. Just copy the files to your Kindle and then follow the simple steps for activating them as screensavers.

The writer of that blog (who incidentally has the last name Kindel) went one step further and added his name and contact information on top of the pictures before transferring them to the Kindle. That way, if his Kindle were ever lost and some kind person found it, they would be able to contact him to return it.
