I made a blender model and animation of this thing I experienced to show how it looks like and moves, and to use that as a way to find out if someone knows what it is, where or why. I don’t know much more and am wondering what others know based on their encounters. It’s somewhere at some time, seems huge. The discs are flattish and don’t reflect light other than from the edges. I’ve tried posting in a few communities and get mostly aggravated answers, or overtly focusing on how I got this knowledge (almost like I’ve done something forbidden when it’s not an aspect I care about), and one got modded hidden.
When artists imagine new things, they don’t generally ask people what those things are as if they must be a thing that really exists in the real world.
The animation you created does resemble something I’ve seen in, I think, a sci fi movie (I don’t recall which). I’ve also seen, in real life, small desktop models resembling this (again I can’t point you something specific, but I’m picturing it in brass). It reminds be somewhat of an astrolab, like https://p.turbosquid.com/ts-thumb/lT/AyGkQ1/TldU6igf/screenshot007/png/1546795156/1920x1080/fit_q87/55f4c2758f661655600a70a3859a1a46059d73cd/screenshot007.jpg but I’m pretty sure I’ve seen something that more closely resembles your animation.
