Since its inaugural year in 2002, the Global Lens Film Festival has gotten around, rather restlessly around, crisscrossing the country from Manhattan to Vashon Island with many far-flung points in between like a Beatnik with a yen for riding the rails. Which is more or less the idea. Except that instead of setting out to discover America, the traveling series of recent Third World cinema -- a cornerstone of the nonprofit Global Film Initiative (GFI) -- is out to help overwhelmingly passportless Americans discover the world.
