Last year, Australia's premier short-film festival — and the world's largest gathering in the name of abbreviated cinema — occurred stateside as a popular adjunct to NYC's Tribeca fest. Tonight, Tropfest gets its own billing. After Aussie pop duo Tamarama kick things off with breezy, beach-inflected ballads, the program screens 16 original films that seamlessly incorporate this year's signature item: the sunflower. Beneath the starry night and amid the airy architecture of WFC Plaza, jurists including actor Billy Crudup and The Tipping Point author Malcolm Gladwell appraise these additions to the heliotrope's artistic history, which already includes Vincent van Gogh's iconic still-life series. Bring a picnic and don't be scared to hobnob with celebrity attendees.
