Tumbarumba is an add-on for Firefox web browsers. It quietly sits in the background, occasionally inserts a fragment of a story into a webpage that is being viewed. The result is an absurd sentence that is reminiscent of the surrealist exquisite corpse game. If the inserted fragment (we call the fragments 'tumbarumbas') is spotted and clicked upon, the entire story will emerge and eventually take over the page. Our intention is for the reader to not only have the pleasure of finding and reading the stories, but also the momentary disorientation of stumbling upon a nonsensical sentence as well as a heightened awareness of textual absurdities (of which only a fraction will be the result of Tumbarumba).
