MakeFan pointed us to a howto for installing the Encyclopodia software, an alternate iPod interface built on iPodLinux which turns your iPod into an offline Wikipedia browser.
Yes that's right. Thanks to iPodLinux, you can now have the entire Wikipedia encylopedia on your iPod. Clocking in at only 1.7 GB of space, it is a very handy tool if you have the sudden uncontrollable urge while out at the shops to discover the capital of Mongolia or the mating habits of eels. The Wikipedia file is updated approximately once every 6 months so you won't have the most up-to-date version but hey it's free and Mongolia isn't going to change their capital anytime soon.
Unfortunately, the iPod Video and Nano devices as well as the Touch and iPhone are not yet supported by iPodLinux. If you have a slightly older iPod, however, it's a simple hack to turn it into a full pocket encyclopedia.
