A LARP-ish workshop

I have been thinking about running a workshop "thing". the basic premise is: you get a character sheet, with background information, and get in character. You have a goal (from the character sheet, and anything you feel like doing) and for the next... 4 hours? ish? you walk around, strictly in-character, interacting with the other people.

The goal is to teach people how to role play characters other than what they normally play (to wit, themselves). As a GM and as an observer, i have seen many people playing the same character every time. As an experienced role player, I have been complained to about this and been asked how to fix it. This is my idea for how to fix it.

Anyone who is interested in helping to create the scenario or characters (I'll need a lot of characters, OMG) should contact me. Anyone who has ideas about format, limitations that may be imposed by Clark, other comments, questions, or suggestions, please comment. Registration is quick and free, and you may already be registered.
