We seek to bring previous javascript experiments with turtle geometry to wiki. We are porting a turtle geometry editor from a previous jQuery-based implementation to a modern ES6 implementation. In our most recent branch we have a proof-of-concept that our editor can save geometry into the memory of a seran-wiki outpost where it can be included in a node-based wiki and forked into the wider federation.
Our first Turtle Spirals arrive in the federation.

These javascript snippets and the associated assets are examples of how one can experiment with self-hosted plugin development.
import('http://dobbs-seran-turtles.glitch.me/turtle-canvas.mjs') .then(({TurtlePlugin}) => { plugins.turtle = new TurtlePlugin(wiki) });
t = document.querySelector('turtle-canvas'); Array.from( {length:17*3}, _ => t.turn().move().nextMovesize() ); t.draw();
