Here is one of my current projects, it's a LEGO theme for iPod Mini.
Using a program called iPodWizard.
I was able to change the images and text on my iPod.

For those of you not familiar with the images on an iPod.
The many bricks are for the battery charging cycle.
The Metroliner train is for the larger battery charging cycle.
The LEGO logo is for when the iPod is transferring files.
It used to show just a circle with a slash.

The Mini-fig head is for the rating of songs, which used to be stars.
The UFOs and the house are for a game on the iPod.
