If you're in Portland, Oregon this coming weekend, I suggest a visit to Esozone 2010, the city's annual conference dedicated to reality hacking, outsider art, occulture, and high weirdness. ("These are a few of my favorite things…") Like last year, this Esozone will be an "unconference" where the agenda is up to the participants. Also, it's free! I wish I could be there, but alas it's not in the stars.
