Where to find "unique" iPod cases?

What style of case are you after? If you want a sleeve why not make one. Very easy to do so with even the most basic sewing skills. That way you get to pick exactly what colour a fabric it is.

 

If you want a sleeve but don't want to make it yourself, I think one of the most unique vendors is http://foofpod.com.

They change their styles frequently, but they don't seem to have anything orange right now.

 

You might want to have a look at Miniot's offerings. I find it rather nice looking.

I can highly recommend Vaja for a leather case: http://www.vajacases.com

They might be a little on the pricey side (or not, depending on your budget), but the leather is excellent quality, the cases are very strong, and I doubt you'll come across many people with one. They're also very customisable - most of their cases come with a choice of 2 types of leather, with a huge range of colours (including orange!), and the ability to have text or a logo on the case.

I've got a beautiful purple case for my mini (with my "logo" on the back), and my partner has a green and black case for his nano. Had them for a couple of years now I think, and they still look great. What's even better is the ipods inside still look great, which I suppose is the important thing about the case.
