Salt really comes in lots of shapes and patterns out of my shaker;

The weird thing is that it doesn’t.

Common table salt is sodium chloride (NaCl) aka "halite". It forms face centered cubic crystals that are very distinctive.

The most common "salt substitute" is potassium chloride (KCl) aka "sylvite", which also forms face centered cubic crystals.

Even the less common sodium malate (Na2(C2H4O(COO)2)) forms cubic crystals.

You’ve got a lot of cuboctahedrons. Nothing edible that I can think of forms those. Very pretty, but I'd be scared to eat it.

No need to be scared, I think. It's table salt coming out of our salt shaker that is filled with standard issue salt bought at a standard supermarket. NaCl with 31mg fluoride and 2 mg of iodine per 100 grams of salt (just looked at the package). Nothing else. It looks like that magnified - AFAIK it's ground, so that may explain the shapes it shows here.
