Screenings begin at the Tribeca Grand in Manhattan (free with RSVP), and will cross the bridge on Saturday to kick off two whole days of feature films, shorts, documentaries, and live music sets. Besides pumping renegade creative vibes all weekend long, it’ll also disprove that prevailing idea that you need a Christopher Nolan-sized budget or a sizable jar marked “Cannes” in order to have your work seen by an audience of more than just your roommate.

Saturday’s event opens at 2pm in Dumbo’s 56 Water St venue, and includes works from several Brooklyn-based directors, a special program on the occupy movement and a live set from DJ Rocket Sam.

The fest concludes Sunday at the Galapagos Art Space with a choice roster of foreign and local films, new work from David Lynch, lo-fi Brooklyn rockers Lavalier, and brain-pleasing visual candies. Damn it feels good to be a zero, again.

RSVP for Friday, Tribeca Grand; Saturday tickets: $8 adv/$10 at door; Sunday tickets: $10 adv/$15 at door

If you’re hitting the road or the skies this summer, plan now for a bon voyage at Flight 001′s sample sale Saturday and Sunday at their Smith St. location (132 Smith St.). The travel store, whose online product menu includes everything from aerotherapy to “jet comfort,”  is celebrating Bastille Day and selling “one of a kind” samples, cds and an assortment of bags. There’s also a packing-themed raffle.

Or brings the kids to the Brooklyn Children’s Museum (145 Brooklyn Ave. at St. Marks Ave.) tonight at 5 for the first of the Target Free Friday Family Jams.

Then come back for the museum’s Sportacular Weekend (Saturday and Sunday), where the family can learn about world sports, fitness and nutrition and the athletes of the animal world (maybe even some aquatic?) through two all-day schedules of demonstrations, activities, lessons and music. 11:30 to 5, both days.

Red Shed Community Garden (266 Skillman Ave. at Kingsland Ave.) in Williamsburg is holding a mega BBQ/benefit on Saturday, with $2 hot dogs, $3 burgers and sausages, free salads and sides, a raffle for dinners and services, a book swap and, oh, yeah, you get to see the workings of an urban organic garden. 1-6 p.m.

Sunday brings the kickoff the Jelly NYC Pool Parties at their new home in East River State Park (no pool here, but there’s some water nearby, so they kept the name). Still, there’ll be DODGEBALL, basketball, food and of course the DJs and bands. Sunday’s line up includes Mission of Burma, F***ed Up, Ponytail and Jemina Pearl. Gates open at 2 p.m., 90 Kent Ave. at N. 9th St.
