Omni-Meta-Creation

I had this notion that it would be interesting to create an evolving, mutating meta-fiction/narrative, that each and anyone could add to at any given moment or time, assuming their interest or otherwise in what had been written before. This would work like sort of like those children's games where each draws a part of a creatures body or a piece of story, consequences I think it was called. This might mean that many would add to the same end of a previous piece, but even so, the effect would be one of a Burroughs/Gysinian cut-up.

It could also be possible to code so that multiple chains fed off in different directions. Additions could vary from words to sprawling essays. The outcome I think would be massively creative in terms of trains and chains of thought, that would be especially interesting to those fascinated by synchronicity and free-form-flow, as I am.

I'm not sure how this would work, and I have no wish to control that (I like to imagine it would evolve); only participate. So ideas please.
