> Already sort of happened in the mechanical watch space. So-called "Tourbillon" escapements, for instance: https://en.wikipedia.org/wiki/Tourbillon https://en.wikipedia.org/wiki/Tourbillon Fantastic (and expensive) works of mechanical movement art, but it goes well beyond this. Some "watches" (the fanciest ones aren't really wearable, but could be considered "portable") contain an amazing number of various mechanical functions and movements (called "complications"), of utter insane complexity: http://reference57260.vacheron-constantin.com/en2/the-worlds-most-complicated-watch http://reference57260.vacheron-constantin.com/en2/the-worlds... Similar such works are done in the clock space as well. I wish I had the wealth to be able to afford such a piece (then again, if I did, I'd probably have a 3rd iteration of the Difference Engine commissioned first - sigh).
