Here are some of the fake O'Reilly book covers I mentioned in a prior post. These have been optimized for use as black & white Kindle screensaver wallpaper images. If you haven't done so already, you can install a Kindle screensaver hack with a couple of downloads.
Update: I've embedded a slideshow from PicasaWeb, but it requires Flash. If you don't see it you can click on the links below to go directly to PicasaWeb.
