omg, thank you SO much for the rec on clickspring's antikythera mechanism! i watched the first two episodes years ago and the algorithm never brought the channel back to my feed. now i'm subscribed and will have to watch this again.
i was also lucky enough to visit athens years ago and see the mechanism in person at the national archaeological museum... it's an amazing exhibit, and if you're ever in that neck of the woods i cannot recommend it any more. :)
