Having seen relatively few in person, and my biggest experience those that I’ve seen I think they come in three main types (so far as motion):
a) Those that spin
b) Those that do not spin
c) Those that do not spin–but have moving lights (phi phenomenon)
In the movie “Earth vs The Flying Saucers” and the Gerry Anderson series “UFO” I think they were all “a” types.
The 1960s series “The Invaders” used “b” types, but occasionally they used “c” types.
The “Jupiter II” might have been a type “c,” but I’m not totally sure.
Any other examples? I’m just curious what has been the most consistent representation.
