For those who were interested in my previous article about aperiodic tiling generation, I've written a sequel, extending the same random generation algorithm to the even newer 'Spectre' tiling discovered by the same people who found the hat tiling in March.
Also, it seems silly for me to make posts here announcing every article of this length I write – especially since I have another in progress already. So I've finally got round to setting up an RSS feed for the area of my website where I publish them. RSS-oriented people should be able to add this to their aggregator of choice: https://www.chiark.greenend.org.uk/~sgtatham/quasiblog/feed.xml
