Digital Silent Night Candles

As I was playing with my phone (Droid X2) I downloaded a candle app. It basically shows a burning candle, and when you move it, the flame moves accordingly. Don't know what you would necessarily use it for, maybe for concerts instead of bringing a lighter, but it's still cool. But it got me wondering: What if instead of using candles during silent night on Christmas Eve we had people download a candle app and lift their phones up instead, a 21st century version of an old tradition? Would love to try it, but also don't want to be strung up by my fingers for messing with tradition.
