Steganography Demo (Hiding Stuff In Stuff)

I love the concept of steganography. Unlike encryption where the message is obfuscated, here the message is displayed in plain text but it's buried inside something else. This isn't going to get you into "super sleuth" grad school but it's a cool trick and illustrates how sometimes objects that look completely normal may be concealing something else. Lots of different ways to do steganography, in this case all you need is your Terminal, a text file and a PNG. Enjoy!
