PhonoPaper is one of those apps that is useless but so cool that it feels like magic from the future when you're using them: It scans printed sound waves, turning them back into music, messages, or any other kind of sounds as you move your iPhone or iPad across the paper. Watch—and listen:

To use it you only need a computer and a program called Virtual ANS to print the sound waves into paper.
