There is a really neat iPhone app out called E-mail 'n Walk that lets you type out e-mails on the background of a view of your camera. It can't take pictures or save anything you see in the background. It's merely meant to allow you to see whats in front of you while e-mailing. With this, you could potentially avoid running into something and embarrassing yourself.
This app could also be useful if you thought you had someone creepy watching you and you wanted to check to make sure. A little weird, but hey, it's kind of neat too!
I would not recommend using this while driving though ;)
