Red Phone Box

This looks like an interesting way to do a collaborative fiction:

Red Phone Box (the English name for phone booth) is a collaborative writing project. The inaugural story, written by Salome Jones,  was published here on Saturday, 28 March, 2011. Each Saturday, another story will be published, written by a contributing author.

Each writer will read what's come before and try to come up with something that adds to, builds on, builds up, or changes what has already happened…
