This guy built a functional version of the mind-blowing Antikythera mechanism with Lego!. I’ve always been fascinated by the Antikythera. You mix that with stuff like the Aeolipile steam engine and I would say that the ancient Greeks had a good shot at producing the industrial revolution 18 centuries in advance.
