Let's go to the beach and make an aperiodic tiling!

The Spectre aperiodic monotile was an unexpected discovery in 2023.

An aperiodic tiling is when you cover a flat surface with copies of a single shape, without any repeating patterns.

Beaches are big and (mainly) flat and, famously, easy to do a bit of temporary building on. We're going to make large “cookie cutter” tools in the shape of the spectre monotile, and cover a beach with the aperiodic tiling.

Update 6

In this video I show the final design of the stamper, including a 3D printed bevelled cutting face, and talk about how we'll coordinate the tiling.

We've confirmed that Beach Access North East will be present on Saturday, and maybe Sunday too.

Even more excitingly, we're going to have lots of tokens you can exchange for a free Di Meo's ice cream! And stickers!

The interactive map is online.
