Email and Walk [iPhone]

Among the millions of apps in Apple's App Store, there are certainly those that are certainly ingenious.

Just check this Email'n Walk for the iPhone, which claims to turn your emailing while walking a bit safer.

How does it accomplish that? Simple...

Instead of writing your email in a white background, this Email'n Walk uses your iPhone camera to show you youre surroundings as you walk. Just like you were typing on a transparent screen.

I can't really vouch for its "safeness", but... considering its a free App, it won't cost you anything to try it out.
