  A few years ago, I wrote an esoteric, minimalistic turtle graphics language called CFRS[]: <https://susam.net/cfrs.html>.

  This was an exercise in making a turtle graphics language that is as minimal as possible. It is closer to Brainfsck than JavaScript and it is not Turing complete, by design.

  Very impressive! In fact, I have come across your website before and I really like how sophisticated the demos are. Thanks for sharing.

  I'd like to take this opportunity to share my own tools that are along the same lines:

  https://susam.net/cfrs.html (Turtle graphics but with only 6 commands!)

  https://susam.net/fxyt.html (Tixy-like but stack-based instructions)

  Hello! This project, CFRS[], is an update of an earlier project named CFR[] which was shared in its own Show HN post in 2023 here: <https://news.ycombinator.com/item?id=37956065>.

  While the earlier project supported 5 commands, this project supports an additional command called 'S' to make the turtle sleep for 20 ms. This little addition can be used to produce interesting animation effects.

  Here are some built-in demos:

  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.

  Since then, I've received a number of creative patterns and animations created using this tiny language by the small and friendly community that has 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!

  Demos contributed by various HNers: https://susam.github.io/cfrs/demo.html

  I enjoyed spending a couple hours with this toy. Constraints lead to creativity, yada yada. Here's the interactive page: https://susam.net/cfrs.html#0
