Macbook Pro cover

I am looking for a cover for my Macbook Pro. It's like the colored snap on ones that you can get from Speck, but in the little area around the apple you're able to customize it. For example, I saw one that was teal, but had zebra stripe in the square around the apple. I've searched the Internet high and low, but not sure where to be able to customize that little box. Anyone know?
