Someone finally hacked the ipod firmware in order to add their own images:
The Wizard’s editor can customize the images and fonts in the firmware contained in Apple’s iPod updaters. Customize the graphics, and then load them onto the iPod when updating the software.
Pretty simple. But beware: the iPod must be wiped, and it’s a hack. Messing with it can mess up the iPod.
What’s next? An iPod running Linux?
