This is a very nice collection of tools and methods. I'm a little jealous, as I was planning to do something like this.
Language is a Virus collects a variety of tools and methods that many of us know, use, and love. It provides tools for doing cut-ups, Exquisite Corpse, Mad-Libs, haiku, collage, and much more.
It looks like a lot of programs I was planning to write have already been written. After a quick survey, I don't see any notes on the page about the licensing status of the software/scripts. I hope the authors have or will release them as free and open source software. I think that's the thing to do to stay in the cut-up / sampling / anti-original-genius spirit.
