Bourke Street: Noon Tram bells clang. Shoppers crowd the busy street. Buskers sing and hustle. Pavement artists conjure visions in chalk. Vendors shout and the befuddled watch. Allegro con brio. Uffizi Florence; Paris of the Belle Époque; 1950s New York, perhaps? And, somewhere among the milling throng, the solitary, unknown eye to varnish commerce to invention; cash to art; and bustle to a time worth looking back. Brendan Frain
