Creative Time, the public art foundation responsible for works like the “Tribute in Light” that shines in remembrance of Sept. 11, has embarked on its biggest project to date. Called “Democracy in America: The National Campaign,” it’s been underway since June coast to coast, with performances at both the Republican and Democratic National Conventions — and it’s curated by Kensington’s own Nato Thompson.

Unlike many political art exhibits this fall, Creative Time’s initiative is as participatory as its theme. When 52 artists gather at Creative Time’s “Convergence Center” at the Park Avenue Armory next Sunday, Sept. 21-Sept. 27, collectives like the dBfoundation will offer workshops on making your own designer, counterculture t-shirts, and artist Steve Lambert will invite people to rejigger the Pentagon’s budget. Performances and speakers like Steve Kurst, Karen Finley and Reverend Billy are scheduled throughout, making it as much a political rally as an exhibition.

“I knew this would be the end of George Bush’s eight years,” says Thompson, “and it seemed like a reasonable time to reflect on the issue of democracy at large in terms of what’s happening to it — or if it’s happening.”

Thompson isn’t the only Brooklynite involved. About a fifth of the artists scheduled to appear at the Convergence Center live here, or will be here this weekend, including:

Duke Riley
You may remember when the Red Hook artist tried to navigate his homemade vessel within 25 yards of where the Queen Mary II was moored last August. Despite being taken into custody, his replica of a Revolutionary War sub was spared, and you can see it in person at the Convergence Center.

The Tactical Ice Cream Unit
A collective called The Center for Tactical Magic disguised this mobile surveillance unit, tricked out with 12-camera video surveillance cameras and satellite internet, as an ice cream truck that actually hands out free ice cream cones. Get a tour at Prospect Park this Saturday, Sept. 14, noon to 6 at the Willink Entrance, at the convergence of Ocean Ave., Flatbush Ave. and Empire Blvd., and coincidentally, not too far from Thompson’s apartment.

Protest Karaoke
Artists Angel Nevarez and Valerie Tevere invited artists, musicians and songwriters to upload songs to anotherprotestsong.org, and now you can sing along to them in Prospect Park, same time, same place.

The Waterboard Thrill Ride
Brooklyn artist Steve Powers’ installation has been up since July beside less menacing Coney Island sideshows: Pay $1, and see an animatronic torturer in action. It should be on view 2-6 on Friday and 2-8, Saturday, Sept. 14, when it closes.
