This stunning animation (created by Eloy Lafuente using the open source software Gource) represents Moodle development as tree, with the root directory at the very centre and other directories as branches. You can clearly see how, in the early days Martin is developing almost entirely alone and gradually more contributors get involved. In addition to developers, in the early years, translators are also shown (up until the language packs were moved to a separate repository).
Many thanks to all our developers, without whom this Moodle ‘tree’ could not have grown and flourished as it has.
