Welcome the latest addition to the App Store, Type n Walk!  This apps allows you to text on the go by “display[ing] a transparent viewport of what’s directly in front of you.”  In other words, using the iPhone’s camera, the app displays a transparent text messaging screen, allowing you to ‘type n walk’ without worrying about tripping on a rock or walking into a tree.  Seems a bit unnecessary; but then again, there’s an app for everything these days.
