R.A. Lafferty's Slow Tuesday Night is a weirdtopia, and so is his Primary Education of the Camiroi. Unfortunately, his "Polity and Custom among the Camiroi" is incomplete at google books, but I recommend getting a paper copy of Nine Hundred Grandmothers-- the collection has some of his best work.

I believe http://dl.dropbox.com/u/5317066/polity-and-custom-of-the-camiroi.txt to be a complete copy.

(And kudos for the Lafferty mentions; he's my favorite obscure author.)
