[syn. Ophioderma pendulum subsp. falcatum]
Puapua moa or Adder's tongue
Ophioglossaceae
Indigenous to the Hawaiian Islands (all main islands)
Oʻahu (Cultivated)
Hawaiian name: Puapua "tail feathers" and moa, "chicken," lit. "chicken tail feathers." www.flickr.com/photos/dweickhoff/13853610635/in/photolist...
The white "dust" on the moss and potting media are the spore of this species, reminding me more of orchid seeds than fern spores. They have been released from the droppy or pendulous (pendulum) fertile spike. www.flickr.com/photos/dweickhoff/14942667182/in/photostream/
Early Hawaiians prepared a cough remedy from this fern. Its spores were given to infants after birth to purge them of meconium.
Etymology
The generic name Ophioglossum is from the Greek ophis, snake, and glossa, tongue, in reference to the fertile spike resembling a snake's tongue.
The Latin specific epithet pendulum, hanging, in reference to this species' drooping blade.

The lighting for Pendulum was simply horrible! I had a blast shooting them though, always wanted to see them live.
In Gerona (Spain) we bought this interesting clock. The radar works are from wood, and there is only one hand. It is not a high-precision clock, but it runs for almost 24 hours, with good enough accuracy. You have to wind it up manually.
There is a US patent for a "flying pendulum" clock from 1883, by Adler Christian Clausen: en.wikipedia.org/wiki/Flying_pendulum_clock
The clock is also known as a Leonardo Da Vinci clock.
Here is the Leonardo museum version: www.youtube.com/watch?v=08sgs6YbLek
"S - XVII" must stand for "Siglo 17", or 17th Century
I can't find anything confirming that this is indeed invented by Leonardo. Looks more like the use of the spring is invented by Leonardo Da Vinci, but the flying ball mechanism is invented by Clausen. (But why would he Leonardo museum show such a clock then?) Anyone who knows more, please let me know.
(Location is where the clock is bought)
This is a pendulum on a grandfather clock that was my great grandfather's. I remember as a kid always hearing it chiming. Sadly it doesn't work anymore. I think that either my brother or I overwound it. I'm going to see if I can take it and have it fixed in the near future.

I'm not thrilled with the final product, but now that I've worn it for the shoot, I might be changing my mind. So warm and snuggly!
Also, it's snowing like a mofo out there today. Supposed to get a foot tonight!

This involved archimedes' pendulum with weights and lights.
42 hours for the pendulum to traverse the circle. It stays stationary, while the earth turns beneath it.
To save the verger having to clamber up a couple of flights of narrow spiral
staircase with all his cassock and full garb on (which he has to wear when on
the site), a motor's been added to wind the clock automatically. This is all
below the cogs and gears in the other photo, and the lower bronze circle in
that pic is where the winding thingy goes.
Before this, in the 30s or thereabouts when electricity was put in the
church, a tiny lift was installed and is still in the corner of this room. But it
doesn't work anymore, as with much early electrical stuff it seems.
The pendulum is the red thing in the bottom left, in mid swing. Weights are
added or removed to the black thingy to make it swing quicker or slower to
fine tune the clock.
