This is an achievement well worth taking a moment to look at. It would likely be difficult to achieve even today.
This will fascinate just about all the engineers, artists, clock makers, doll makers, computer programmers, want to be inventors or basically anyone out there who likes to tinker. Enjoy. It is truly amazing. Remember this was built in the 1760s, or about 249 years ago.
