When it comes to properly spreading holiday cheer, an ugly Christmas sweater just isn't enough anymore. You've got to up your game, and nothing guarantees gameupmanship like floating around your office holiday party brandishing these festive light-up iPhone cases. They're not only a classy way to protect your device, they also don't require their own power or light source.
What kind of Christmas miracle is this? The miracle of science, of course. Using the same principles as fiber-optic tables, these clear plastic cases from VanD harness the light from your iPhone's flash to internally illuminate, revealing etched patterns and designs.
So while technically the cases don't leach power from your iPhone, they'll still require the flash to be on which isn't doing your battery life any favors. But thankfully they come with a $20 price tag which perfectly matches their novelty value. [iCella via GadgetReview]
