Got an iPhone? Or any cell phone for that matter? It's time to grab a few friends and run to the nearest scanner or glass door.
Just like you used to do in the days of high school photocopiers: Press your face up against the scanner or glass and have someone take the photo from the other side of the pane. Once you've captured the goofy "stuck in a box" picture you can assign it as the contact photo for that person on your cell phone!
The images look most hilarious on the iPhone's glass screen, but will still elicit giggles when used on other models.
