“Tumbarumba”, a project by Benjamin Rosenbaum and Ethan Ham, is an anthology in the form of a browser add-on. To read the stories, readers must stumble upon them while browsing the web. The browser add-on will occasionally insert a story fragment into a webpage as it loads it. The result is a disorienting surreal sentence that sometimes is nonsensical and sometimes amusingly close making sense. If the reader spots the fragment, they can interact with it in a way that will cause the full story to appear—albeit in the format of the webpage on which it was found.

The authors in the anthology are:

* Haddayr Copley-Woods
* Greg van Eekhout
* Stephen Gaskell
* James Patrick Kelly
* Mary Anne Mohanraj
* David Moles
* John Phillip Olsen
* Tim Pratt
* Kiini Ibura Salaam
* David J. Schwartz
* Heather Shaw
* Jeff Spock
