Script Writer

I am a member of an improv troupe called The Improvables (www.theimprovables.com).  During our last show we tried out a new game called Script Writer, in which one player (it was me that time) starts telling a story as if they are writing a book, while the other players act out the scenes he is describing.  It worked out pretty well, and it was a wonderful exercise in instant, creative plot-creation.  Next time I have writer's block, I would love a chance to play that game again.
