I figured since this uses a ball-bearing to generate sine waves
(mechanisms like that have been seen here now and then), this would
have some interest:

Whups- the ball is for an integrator, jumped to that because that's
the part I recognized.

Yeah, the olde "ball and disk integrators" I remember seeing gathering
dust in the corners of some labs when I was in college.
I think they were WWII relics from mechanical analog computers used for
weapons aiming or something similar.
Beautifull machining though isn't it? She(?) must be one in a gadzillion.

I guess NASA, The New York Times and the Earth Observatory section at
NASA are also "righty wackos"

Did you read the NASA news release, or just the Newsmax rehash of American
Stinker's rehash?
It may be too complicated for those...uh..."journalists." The story is that
the PDO cycle this time is likely to be a long one (their ups and downs have
been tracked for decades, so they have some knowledge of these things), and
the temperatures resulting from the PDO cycle are likely to swing widely
enough to mask the global warming trend. Also, locally, the effects of a La
Niņa can push the evidence either way.
Our "journalists" used this as evidence that something is wrong with the
research climatologists at NASA. Of course, these "journalists" have a deep
knowledge of the science involved. Right....
