Formicarium (latin for 'place of ants') is a wikiwidget meant for Wikipedia articles about Langton's ant, one of the best known cellular automata. It can be seen live in the article Hormiga de Langton of the Spanish Wikipedia, and you can also load it in this very page by clicking .
If you want Formicarium on your wiki, first enable WikiWidgets and then recreate the Template:Formicarium in your wiki. Once done, you will be able to insert Formicarium into any page by just using the template.
The code of Formicarium is served from Commons (MediaWiki:WikiWidget-Formicarium.js and MediaWiki:WikiWidget-Formicarium.css) but the development is done via Phabricator and Gerrit. The code can also be found at the GitHub mirror. The main developer is Sophivorus.
