In plain words
CFR[] is a minimal drawing language that uses just five commands—C, F, R, [, and ]—to create graphics. Designed for anyone interested in simple, constraint-based programming, it strips drawing down to its essentials, making it accessible to programmers and hobbyists who enjoy exploring what can be achieved with minimal syntax. The language appeals to those curious about esoteric programming languages and generative art through extreme simplicity.

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…

Today I am here to show my first release! It is heavily inspired by OpenSCAD which got me hooked on the idea of a CAD programming language and what it can do. Please let me know what you think. Ill be in the thread to answer any questions you may have.
