I use two things of geomtric property, the first one is called crescents by Twitter@.GirihApp https://twitter.com/GirihApp/status/1100842480101146626 , the second one is called squiggles by Twitter@.HypercubicPeg https://twitter.com/HypercubicPeg/status/1102607076902273025 . And now, I'm practicing English writing!

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

Recently I made several tiling images using regular heptagons or 14-gons etc.

The image is combined "Olympic symbols" https://en.wikipedia.org/wiki/Olympic_symbols and "Tokyo 2020 Emblems" https://tokyo2020.org/en/games/emblem/

Japan has become a New Year, Congrats!

I made image like before again, using the triangle of lengths's raito \(37:13:\sqrt{2019}\) (similar to "Eisenstein triple" https://en.wikipedia.org/wiki/Eisenstein_triple#Triangles_with_an_angle_of_120%C2%B0 and me https://twitter.com/wasanp_/status/1049256994228428800 ) #justfit
