Snowflakes are a good example of the fact that thermodynamic entropy isn't the same as "order" as perceived by humans. The snowflake has higher entropy (2nd law) than the water + air system that formed it, even though it looks far more organized. https://twitter.com/ZonePhysics/status/1160843941857648640 …

it's wrong though. The crystal (ordered) does have a lower entropy. The entropy of the (closed) system didn't change.

But it's easily resolved by thinking about processes and not things (not as good a framework). Then you can read the original tweet as saying, even though the process of generating a snowflake seems to increase order, it comes at the expense of also generating more entropy.
