I've finally made a full-size spectre shape! And for Maths Week England I'm going to talk in some primary schools about tessellating shapes.
The aperiodic monotile was an unexpected discovery in 2023, and there have been several demonstrations constructing it in real life, such as the foam tiles produced for TMiP 2023. But making individual tiles limits you to the number of pieces you have.
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. There may also be ice cream.
The project is currently in the early planning stage. Once we've picked a time and a place, we'll be looking for volunteers to come down to the beach and do some aperiodic tiling, and talk to the public about what we're doing. If you're interested in being involved, join the ridiculous maths project volunteer mailing list, and we'll contact you when we're looking for people.
