folding story : the group storytelling game
This is a brilliant take on a classic childhood game. Remember? Write a line of a story, fold it over and pass it to the next person who writes the next line...and so on. It's a perfect fit for an online interpretation.
In fact, it's childhood friends of mine who started FoldingStory, "The Group Storytelling Game." It works just like the paper version. But with a few more bells and whistles. Pick the story you want to add a line to; browse and read other stories for a good laugh or potential awe; or start your own story with a great opening line.
