If those white earbuds aren't doing their job to get your iPod stolen, you might consider the mi Lite. It's half protective case, half party in my pocket, and fully obnoxious to fellow commuters on the subway.
mi Lites are activated by a touch sensor on the case and provide their own "replaceable" power supply (we are guessing watch battery). The site claims future availability for all iPods but the mini and shuffle. We'll need to see mi Lites in person before any final judgments, but most of the designs on their page are ugly as sin - like sticking your iPod in a glowing pile of poo. But the model pictured here isn't bad for $19.98.
