B Ark is a one-night live-action role-playing game set in the universe of the Hitchhiker's Guide to the Galaxy trilogy by Douglas Adams. The game is set aboard a ship of the Golgafrinchan Ark fleet sent to colonize a new world (probably familiar to those who've read the books, and meaningless to those who haven't), though strangely enough a large number of seemingly unrelated characters are likely to show up. The game is being written by Andrew Twyman as a project for 21W.765J (Interactive and Nonlinear Narrative with Professor Janet H. Murray) and will later be run under the auspices of the MIT Assassin's Guild, probably in the summer or fall of 1998.
If you think you may be interested in playing, take a look at my blurb for a quick introduction to the game.
