No, this one is nothing like scifibigbang ...it's simple, fun and addicting (well, for me anyways, LOL)

I give you 10fics_10words .

Simply put, you write ten fics in ten words. There is a list of categories (angst, AU, etc.) and you write a fic for it.  Write a set for a pairing, a character, whatever. So go, have fun and let your creative juices flow. 

You never know when one of them sentences will prompt an entire fic. :D :D
