Looks like an Eddington Algorithm (likely misnamed, but taken from Eddington's quote about monkeys typing Shakespeare). It's done by hashing the entire text and then randomly stepping down a line. The size of your step (one word, two words, etc.) effects readability. I recall once seeing somebody's bot use this algorithm to occasionally spew out the bible on a religious chat channel. Drove the locals nuts.
I like the idea. I think it would be better illustrated with shorter lines, though.
Language processing may give rise to something wonderful. Interesting work.
