The MirrorCase for the iPhone lets you take photos while holding the phone flat, like an old-timey camera. It seems like a good way to shoot video of yourself, too - just set it on a table and do your thing. At $50, it's a bit pricey. I wonder if there's a DIY version? (I think this is the gizmo used to secretly tape Mitt Romney declaring that 47% of Americans suck.)
