Olympus macro 38mm f/2.8, snowflake around 1mm in diameter and probably around 1/5th of human hair thickness, barely noticeable and yet at that thickness there are protuberances  on it.
Magnification 4:1
First time I'm seeing this particular star formation.
More to come

Being a scientist myself, I always have wondered how the molecules crystallising on one side of the crystal know exactly how to arrange themselves so that they "mirror" the molecules on the other side of the snowflake ... Must be some kind of non-localised force or field ...

We still haven't figured out how gravity works, either. We are aware of the cause and effect, and the rest is still in the theory stage.
There's a bit of a list of factors to the creation of a snowflake. It has been said that no two snow flakes are identical twins, either.
I agree on the imagery! The copy-right signature stuff would work way better away from the subject, though.

Why must be? My intuition tells me that once seeded, the growth proceeds according to the "vibration" of that growth communicated throughout the crystalline structure. I don't know but intuit both sides grow simultaneously.

I ask myself the same question : How?
Each time I'm blown away by the design and symetry.

The center of that one reminds me of a logo for Asahi Optical Co. (later Pentax Corp.).
Here's an example from one of my lenses:
