Although I haven’t gotten my hands on a Kindle yet, but I’ve already investigated ways to hack the device. Obviously cracking the cover open would void the warranty and may possibly put you in violation of the license for the 3G connectivity. The site below has the lazy hackers way of impressing friends and family by using hidden functions.
The site Reversing Everything hacked into the operating system for the device (Linux based) and found some hidden functions and programs built-in. Personally some of them look pretty cool, my personal favorite is the built in GPS/map.
Here are some of the secret keyboard shortcuts:

due to an implementation bug, screenshots can only be stored on SD card, not the main storage. A gif file is saved in the card root.

Enabled only if allow_demo=true is passed on the Java commandline. Needs a special demo script present on the SD card.
