"The Hat", a shape that tiles but never makes a repeating pattern (infosec.pub)

A square can tile a plane but can form a repeating pattern. Is there a single shape that can tile but never repeats? That's what's called the "einstein problem".

Link to the article

In 2010, the first never-repeating tile was discovered: the Socolar-Taylor tile. But it's a bit weird, having several separated, disconnected bits.

In 2022, "The Hat" (shown in pic) was discovered, and it's a lot less weird. It only has 13 sides and nice angles that are multiples of 30°.

I wonder if there's a way to apply this pattern to create some specific kind of cellular automaton.

Honestly idk enough about this stuff to even know if that's a dumb question, but at the very least, the image reminded me of that.
