Gladly would like to share that assignment for the introduction is done! Have taken some time for brainstorming and looking for ideas and inspiration for this task, but happily I am done.

Came out with this picture, made with pencil and ink pen. First idea was to illustrate Moodle as electric wires connecting, supplying and sharing the goods through all of us, but after some more brainstorming came out with other keywords, as roman forum, human and a book.
