I recently bought a bottle of Crystal Head Vodka, purely because I used to be rather obsessed with Arthur C. Clarke’s Mysterious World. I had 20 or so VHS tapes my Grandfather gave me as a kid (now lost). The intro of every show featured a crystal skull. They do a whole show on crystal skulls in which they claim that even with todays modern technology we can’t recreate on as nice as these old ones that we just found.
I don’t think this was mentioned in that show, but the Antikythera mechanism is friggin fascinating.
