Some may say that there are two very distinctive geeks in this world. The iPod geeks, and the Linux geeks. Now the two have merged ceremonially in a really awesome way!
What if I told you that there is a Linux operating system that you can install on your iPod? Don't laugh, I am dead serious. I just found out about it today. This open source bad boy is called Podzilla and is a part of the iPod Linux project.
Fom the iPod Linux Project:
iPodLinux is an open source venture into porting Linux onto the iPod (http://www.apple.com/ipod/). So far, we have successfully ported a customized uClinux (http://www.uclinux.org) kernel to the iPod, and written a simple user interface for it dubbed podzilla. Additional applications and modules have been written, adding many capabilities not found in Apple's firmware.
Here is a video I found on Youtube to give you an example of what Podzilla looks like on an iPod nano:
Don't run off and get your double geek on just yet. Not all versions of the iPod are supported yet. To find out if yours is supported click here: (Supported iPods)
