Spiffing up the Pump?

So I have had my pump for over 7 years, and as much as I love it, I often see it and think "it looks so plain...". Being a college stundent, a girl, and a music student, I like to keep everything in my life colorful and different. I have the skins from skin-it, but they are a bit expensive to change very often. So I was wondering if anyone knows of things like cases and accessories to spiff up my pump some?
