Afaict, any ellipse in 2d can be reconstructed as a circle rotated in 3d.

Does this work for you? You should be able to fly around it and explore.

Circles rotating in space is a neat theme.

Circle inversions might come in handy.

For some reason, I am thinking of a cylinder that holds spiral arms
rotating as a base object. Construct a circle multiple rotating
cylinders, well, it might give the look. The fun part is that I can try
this out when I get some more time, perhaps even tonight.

This should do it, humm... It should work fine and reproduce the effect.

A circle is broken up into n cylinders. Each cylinder has n spiral arms.
Each cylinder is rotating.

Here is a base with a 16-ary setup for a circle. Now, each cylinder
needs to have spirals arms coming off of them with circles on the ends.
Well, rotating them should give the effect shown in the video you linked to.

I have never been familiar with necrophilia. Fwiw, this screenshot of my
3d experiment with circles looks interesting to me:
