One of the objects is very similar to a previously posted photo from a

Sorry for going all retro, but on #931 from last week or so (the 3-phase
wire hanger), what's with the swirly Art Deco styling? Is it just that
this was designed in the days when Deco was all the thing?
I think that the purpose was to give longer "creep paths" for
current to flow when it is wet -- e.g. from rain or ice. This allows it
to operate at a higher voltage than a straight '+' shape would allow.
Also less chance of someone interpreting it as an upside down
Cross, and calling the power company "Satanic". :-)
Enjoy,
