There are tons of reliable iPhone cases out there, but why settle for one that simply covers your device? Case manufacturers are getting more and more creative, offering iPhone shells that can double as stun guns, brass knuckles, and even thermal cameras (you know, for hunting ghosts). There are also plenty of cases that simply look wacky, for the extra-expressive user. Here are 15 of our favorite iPhone cases that break from the norm.
At $349, Flir is one of the most expensive cases around, but what other cover allows you to hunt for ghosts? This thick, soft-touch case looks unassuming at first glance, but it packs an internal camera that transforms your iPhone 5 or 5s into a fully functional thermal-imaging device. Once calibrated, Flir allows you to read heat signatures in real time using the Flir app, and the case's 1,400-mAh battery can be used to juice your phone.
