Inside/out, outside/in

Continuing from this post, I prefer the following symbol though, since the basic categories are akin to the objet a at the center of the diagram. I.e., they are that which traverses all boundaries which being at all boundaries.

And yet the following gif shows the dynamics in action, how the inside center is always moving out, enfolding the general/particular. And simultaneously the outside is always moving in, being infolded by the concrete. All kinds of folds going on. It's a bit harder to imagine how the above looks translated into the below, since the edges are rounded and no corners.
