I once made a word-based Markov chain and fed it a corpus of my instant messages. I did that to amuse myself. I did that too crudely, though; I didn't give it any notion of beginning or ending a sentence (although I kept capital letters and periods as part of each token, simply because that was easy to do). I don't think there were any other corpuses that I did that to.
