Pirates are Broadcasting Troll Faces on Russian Military Radio
A slightly different concept but to "hide" data in other files (images/audio) is steganography or this cool opensource tool called steghide http://steghide.sourceforge.net/ Interestingly if you do it with audio files, tools like my eXtace (extace.sourceforge.net) (a realtime FFT visualizer for sound) will show it quite clearly in the frequency domain whereas it'll be pretty much invisible in the time domain.
