One of the most exuberant, exhilarating films you'll see this year is a celebration of unbridled creative expression -- and you can watch it online, for free, right now. ---

Director Jacob Krupnick's Kickstarter-funded Girl Walk // All Day is a hard project to summarize: part music video, part experiment in audience-participation documentary, part oddball romantic triangle. The 70-minute film is set to the entirety of the album All Day by mashup artists Girl Talk, itself a musical "found art" piece mixing music from dozens of artists including the Ramones, Electric Light Orchestra, Peter Gabriel and Black Sabbath with hip-hop lyrics by the likes of Jay-Z and Ol' Dirty Bastard. But the "story" is its own wildly original creation, following an unnamed dancer (Anne Marsen) as she flees the restrictive confines of a ballet studio to dance her way to the Staten Island Ferry and across to Manhattan, launching a dizzying all-day performance.

There's a modicum of plot in the girl's story, as she eventually interacts with other "characters" who are in on the creation of the film, including Dai Omiya and John Doyle as a pair of men who pursue her at various times. But Marsen also spends much of the film trying to pull the everyday New Yorkers she encounters into her performance -- generally unsuccessfully, but when she does manage to find willing participants, there's such an exuberance to the spontaneous result that Girl Walk // All Day becomes one of the best case studies ever for crowd-sourced art also becoming crowd-created art.

At the center of it is Marsen, who should become everyone's new art hero: Not only spinning her high-energy one-woman choreography through New York City landmarks like Yankee Stadium and Chinatown, but beating her fists against the seen-it-all complacency of Manhattanites to create new in-the-moment art. It's the kind of work built on pure love of creation, and it's hard to resist the smiles it inspires.
