In 2005, Provflux staged a fashion show runway across the Providence River. Tomorrow there's a "Ferry Fashion Show :: time TBA :: top deck of the Block Island Ferry" from Point Judith.

Provflux V -- billed as "urban adventures in psychogeography" -- is under way through Sunday. It's all free.

Part carnival and part conference, ProvFlux brings together artists, theorists, urban adventurers and the general public to share their visions of what the city can be, and to take action to make it a reality.

The simple premise behind ProvFlux is to create an environment of positive activity, and to continue expanding upon the ideas of what one can do in their city. It exists to invite people from all walks of life to meet on the common ground that is our city streets, in an unjuried, completely free and 100% participatory environment.

Although the festival decamps to Block Island today, the global campground and hq is at
Monohasset Mill, 532 Kinsley Ave., near the Steel Yard.

Saturday's highlight: The Second Annual ProvFlux Lecture Series and Sacred Garden Photographs by Seven Arrows Herb Farm co-founder Michel Marcellot, at Firehouse 13, 41 Central St. Tsunami Victim's Orchestra plays at night at a secret location.

Sunday, there's outdoor yoga on the Statehouse lawn at 1 p.m., and Kickball Jesus presents the Lovers Vs. Heartbreakers Kickball Challenge from 3 p.m.-5 p.m. at Amtrak Station Park.

There's a lot more: Here's the complete schedule. More than 400 photos at Flickr tagged Provflux will give you a flavor of what's about to happen. More idea in the FAQ.

It's the fifth annual Provflux created by PIPS (Providence Initiative for Psychogeographic Studies), which organizes "urban interventions."

About an earlier Provflux, Meredith Younger, a Provflux organizer, said ""In this digital age, friends are made online." We're trying to bring it back to the real, visceral experience of actually having a conversation face-to-face. Even that's becoming a radical idea."
