I was thinking perhaps of a hypothetical festival where you show up naked but the festival itself provides everything to everyone equally. Walk in the door and there's 53' trailers full of goodwill-like clothing, tons of raw food ingredients for the cooking, hand tools and wood for building etc. In short, everyone arrives in a new "world" as equals and makes of it what they can. Bonus points for not allowing real names or talk of who you were on the "outside".
Oh crap. I'm kind of describing prison. So umm... like jail but not so sucky.
