    @mattblaze@federate.social I hadn’t had my morning coffee and my first thought when I saw this photo (of the rotary converter) was “oh, that is a top view of a Curta calculator.” (I used to be pretty good on a Curta.)

        @mattblaze@federate.social @karlauerbach@sfba.social continuing the theme of misunderstanding what you’re seeing, I saw that and was thought it was a clockwork camera lens for a second (not that I think there is such a thing, but my brain isn’t that quick today).
