Tempus Fujiting
An 'Anniversary Clock'. German, 'Urania', just a bit later than 1905, the year of publication of Einstein's Special Relativity paper, which had a bit to say about clocks. But time is not slowing, it's speeding up! The internet radio behind it is about a century younger.
These torsion pendulum clocks could run for a year or more on a single wind, hence the name. The were often given as wedding presents from husband to wife. Only eighty windups to a Ruby anniversary. But many more adjustments -- more pretty than precise. Watching their dawdling oscillations has the same calming effect as fish in a bowl...
I haven't played around yet with ISO overrides, neutral density filters, or time exposure settings on my digital camera. So I failed at first attempt to do what I wanted here (and would have easily done with my old analogue cameras), to blur the rotating pendulum. The camera had an extra degree of freedom and aims beyond mine. It did the equivalent of push processing by upping the ISO to 6400. But the pseudo grain seems to me OK for the context.
Within the (1/80)s exposure, the pendulum would have rotated around a third of a degree. This model has a relatively unusual cylindrical inertial base, so not much blur could be expected to show up on that part in any case. Maybe I'll have another go with different settings in another few million oscillations or so...
