The good news: I have found photos of what is undoubtedly the most awesome iPod case ever, thanks to Make Magazine's blog.
The bad news: Like most stuff featured on Make, you can't buy it anywhere.
Flickr user sirljohns has put up a sort of tutorial of how to make a fully functional iPod case out of an old Game Boy console, but you'll still need a good amount of technical know-how in order to build one yourself. Nevertheless, this is about as cool as it gets.
