This document 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 README.md.
If you create an interesting demo that fits in 64 bytes of code,
please create a new post and share it with the community. If
the demo looks interesting, it may be added to this document.
Contents
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!
