If you're prone to getting spinach stuck in your teeth, then Senko has a product for you. ScreenMirror is a sticker that makes your cell phone (or iPod) screen reflective when the backlight is off, which is great for checking those pearlies before snapping a high-res self-portrait. When the phone's backlight is on, you can see the screen beneath the sticker — but only if you're holding the phone within a 45° cone. The "advantage" of this specific angle feature is that nobody to either side of you can see what you're doing with your phone, similar to the PodCowBoy. Are you afraid that the stranger sitting next to you on the train is cribbing your friends' numbers as you scroll through your address book? Is that even possible? This feature doesn't seem terribly useful, but on the other hand, if you're ashamed that you still have Jewel's "Pieces of You" on your iPod, then it may be worth 19 bucks to shield your playlist. — S.E.
