Everyone loves the story of the discovery earlier this year of the new "hat" aperiodic monotile.

Now you can dive deeper with the videos that have just been released from the "Hatfest" conference held back in July here in Oxford.

Intended for the general public, there are talks from two of the authors of the original paper, and much else besides:

The origin of the Spectre Dress
#hatfest #aperiodic #transpride #fashion #math #openuniversity

So the origin of the spectre dress is relatively mundane and silly. Following a rough period of early transition (I started in 2022) I felt like I was finally starting to hit my stride and could feel my confidence growing. I'd purchased a trans pride-themed dress from an Etsy seller earlier in the year which had been attracting a lot of positive attention, and since I consider my transition and my journey through mathematics to be intimately related, I wanted to combine the two.

Originally I wanted to contact Stefan Pautze [http://pautze.de/] and use a colour variation of one of his designs (rough version pictured), as I've always been a huge fan of his art and I'd also met him in-person at the exhibition in memory of Uwe Grimm in 2022 where we hit it off. At this point it was still just a kernel of an idea, nothing concrete. But then two things happened in a short span of time. Hatfest was announced, and the spectre tiling was discovered about two weeks later. The idea for the dress instantly crystallized, and I got in contact with the same Etsy seller who did my pride dress to ask about a custom design. (0/8)
