An app for the rest of us

I had a brilliant idea tonight.

Wouldn't it be hilarious if there was an app for people's iPhones and BlackBerrys that showed them on screen what's coming up in front of them? Cause I mean, apparently it's really hard to look away from your phone as you're walking down the sidewalk. I'm getting really tired of people too busy with their phones to watch where they're going nearly running over me. The app could use the camera that's already there, and go full screen, or maybe even screen-in-screen, so you could play solitaire or whatever is that is SO demanding AND watch where you're going at the same time! Call it iMWatching, or iKnowWhereiGo, or something...

Let the record show that this was my brilliant idea, and when somebody actually invents it, I want a cut, mmkay?
