For even more “fun”, try opening a file in Audacity / Tenacity, which will default to raw mode if it can’t tell what a file is, and you get to see the waveform and so on. Just take care not to modify and save over an important file with that.

Well, unless that file (though, work with copies of course!!) is a .bmp image. Then try applying some “audio” affects to sections or the whole thing and see what it does to the image and export it, can get some neat stuff.
