TIDAL THE VIVIAN,&amp;nbsp;Matakana April 16 – May 28, 2016   TIDAL is a meditation on the littoral zone--with its flotsam and jetsam, currents, rips and backwash, its convections and processes of rising and falling. The works explore how humanity is placed within this endlessly changing schema and what we leave behind: footprints in sand, the wake of a kayak, an echoing conversation, traces and trails of being. The exhibition features work by Phil Dadson, Bruce Foster, Ian McDonald, Gregory O'Brien, John Pule &amp;amp; Elizabeth Thomson.
