Street art in Melbourne, Australia

Melbourne, Australia, is emerging as an epicenter of street art. Bernadette Alibrando, of Walk to Art, has her finger on the pulse of the burgeoning scene. Alibrando leads tours that wend into and about the city's many "laneways" (Australia-speak for "alley") where artists post their works. Among the stops on the twice-weekly tour is the artist-run Citylights installation on Hosier Lane, where rotating exhibitions are displayed in lighted boxes for 24/7 viewing.
