As a longtime fan of tiling

 

Years and years ago, I was fascinated by an article about the Penrose tiles. It dates back to when Scientific American still had Martin Gardner writing a column called "Mathematical Games".  

It's listed here, along with some of the other great columns.

That article, however, doesn't link to the original article. But there's a long excerpt here.

That isn't the subject of this article, but tiling is. Because, in 2023, an amateur hobbyist discovered a single tile that tiles the plain non-periodically, essentially the ultimate prize in this particular pursuit. 

Wow!

Then he found another one.  They are called "the hat" and "the turtle". 

You can even get sets of them on Etsy already.
