Show HN: CFRS[] Community Demos: Patterns with turtle graphics using 6 commands

Hello HN!

Back in 2023, I introduced CFRS[], a minimalist drawing language with turtle graphics, featuring just six simple commands, through a "Show HN" post (https://news.ycombinator.com/item?id=37956065).

Since then, I've received a number of creative patterns and animations created using this tiny, esoteric language by the small and friendly community that has since formed around it. In this post, I intend to share some of these interesting creations with everyone to highlight the ingenuity of their creators. If you create an interesting demo using this language, please share it in the comments--I'd love to see it!

Cool demos! Interesting to think of these not as 64 byte programs, but something like 24 bytes or less (<3 bits each for the 6 symbols).
