Kant Generator

Kant Generator produces text that vaguely resembles that of Immanuel Kant's Critique of Pure Reason, using a generative grammar originally developed by Mark Pilgrim for his version of this app. The text generated is grammatical, but usually nonsensical, and almost always amusing. It does make some dandy placeholder text if you're not a fan of Lorem Ipsum.
It also generates Thank You notes, Excuses, Grumbles and Tweets that are similarly nonsensical, but just a tad more practical.
