Otherwise known as The Church Of What's Happenin' Now
The Burning Man is a no-holds-barred New Age "Woodstock" style festival, where neo-pagans, wiccans, transvestitie entertainers, and back-slidden Christians go to trance, perform rituals, burn sacrifices to pagan gods and goddesses, dance in the nude, engage in sex, and otherwise "express" themselves and become one with Gaia. Attendees set up theme camps such as "Lost Vegas," "Motel 666," and "Crucifixion With a Celebrity" (where one can purchase a picture of a crucified obese Elvis). Hamburgers are sold by devil-worshippers at the McSatan cafe, and T-shirts are available that proudly proclaim, "Praise The Whore." related thread.
Groovy (but not particularly Christ-like).
