Clockpunk Difference Engine

One of the unexplored ideas (as far as I know) in Clockpunk is the absence of a Clockwork Difference Engine. Given that people in Greece as far back as the first century B.C had the technology to build devices like the Antikythera Mechanism, the possibility of an earlier Difference Engine exists. Imagine a difference engine build by the great master himself – Leonardo’s Difference Engine. I may be writing a short story on it soon, so stay tuned.
