CFRS[] Community Demos

This page contains a collection of CFRS[] demos contributed by community members. CFRS[] is an extremely minimal drawing language that consists of only six simple commands: C, F, R, S, [, and ].

To learn more about CFRS[], visit susam.net/cfrs.html or read the manual at github.com/susam/cfrs.

If you create an interesting demo that fits in 64 bytes of code, please create a new post here and share it with the community. If the demo looks interesting, it may be added to this page.

Dynamic Demos

Dynamic demos contain the S command which makes the turtle sleep for 20 ms. This is often used to produce animation or dynamic effects in the demo. The following subsections present a collection of dynamic demos created by various community members.

Static Demos

Static demos do not contain the S command that makes the turtle sleep for 20 ms. As a result, the static demos are rendered synchronously in a single stroke. The following subsections present a collection of some nice static demos created by the community of CFRS[] artists!
