Perhaps you've experienced the burgeoning arts scene in Brooklyn firsthand -- the galleries, the artists, the musicians, the deejays. Or maybe you've never set foot in the hip New York City borough. Whatever your coordinates, you can now log onto a new online journal that attempts to prove Brooklyn is a state of mind. Entitled bkyn, the Web site features content ranging from digital music (think DJ Spooky's urban sound collages) to links to Net art projects (think Mark Napier's browser art) -- work that's not defined by location, but reflects the spunk and creativity that's associated with Brooklyn.
