I came across this series of videos yesterday and wasted the entire afternoon watching them. Amazing and addictive!
First in the series:

Also watched all of the supporting "Antikythera Fragments" videos showing tool-making and methods for the main series.
I read elsewhere that the series is paused because the maker discovered something previously unknown about the Antikythera Mechanism and is working on publishing the findings.
