It was the perfect way to spend a beautiful summer’s evening, walking through the Auckland botanical gardens with friends, admiring the various pieces of sculpture scattered throughout the extensive space. All one’s senses were engaged – plants, flowers and works of art to look at, the aroma of herbs on the breeze, birdsong and the sounds of children playing, the smooth lines of some of the sculptures inviting you to touch them. One work called Lens had a granite disc in the centre, which was warm to the touch despite the heat having gone out of the day.
