I've posted The Matter of the Monster, a very small choose-your-own-adventure-style story that I wrote for the Indigo New Language Speed-IF challenge. (The first version I posted was buggy on Firefox, but I think I've fixed that now.) The new language I used -- new to me, that is -- is Undum, a Javascript CYOA toolkit. I had to hack on Undum a little to get the effect I wanted; you can download my toolkit changes here.
