iFog for the iPhone

A buddy of mine has developed a pretty cool iPhone app called iFog.

The app allows you to take a background image and blow into the iPhone’s microphone, which fogs up the screen. Then you can write little messages on it, like a fogged-up window.

The coolest feature is Secret Message, where you write a message on the screen, and it doesn’t become visible until the recipient blows into the mic (fogging up the screen and revealing the secret message). Could be pretty useful in picking up on members of the opposite sex.
