@jsiehler I'm playing your #SlidingBlockPuzzles with so exciting! http://homepages.gac.edu/~jsiehler/games/Blocks-App/index.html (If I understand mechanism that one piece moving one time anyway is counted as 1-move, I may be able to reduce MOVES more!)

The best memory of my internet life is that #twitter https://twitter.com/takatasennsei taught me the attached images. In Japanese, it seems to be well known as "3×3の完全虫食い算一覧" https://www.gensu.co.jp/saito/puzzle/a65worm3.html

Our paper "Random triangles and polygons in the plane"] – in which we give a novel answer to Lewis Carroll's question "What is the probability a random triangle is obtuse?" – was published recently in the American Mathematical Monthly: https://doi.org/10.1080/00029890.2019.1535735

Here's an animated version of Figure 2 from the paper, showing a geodesic in triangle space. The geodesic starts at the equilateral triangle shown, and the three curved paths show the tracks of the three vertices.
