I made some custom screensavers for my Kindle 3 AKA Kindle Keyboard (600 x 800 px) and thought other people might want to use them too :)
I also made others based on fan art I found on Tumblr but I wasn't sure about posting them since they're based on other people's work. Never thought it would be so damned HARD to find high-resolution portrait photos >_<
