This year the festival will include films not only from Wingspan but also from other city organizations and one from a middle school in Arlington， Virginia."We want to make this a national event."Ms. Gardner added. The nine shorts to be shown range from a Claymation biography of B. B. King to a science fiction adventure set in the year 3005. "A lot of the material is really mature，" Ms. Gardner said， talking about films by the New York City branch of Global Action Project， a media arts and leadership-training group. "The Choice is about the history of a family and Master Anti-Smoker is about the angers of second-hand smoke."Dream of the Invisibles describes young immigrants'（移民）feelings of both belonging and not belonging in their adopted country.
