Nina and her two flatmates are students on Canterbury University studying biochemistry, engineering and law respectively. According to century-old customs the lectures of the last Friday of the term have been cancelled. So the girls take a leisurely stroll giggling away in the sunbathing inner city. Among complex steel structures of overwhelming size they discover the Urban Living Wall exhibiting tiny, unique plants of a special New Zealand bioflora. This is a project made of native rocky outcrop plants, 3D printing and CNC cutting, felt, and more to create an artistic, refreshing environment in Christchurch City.
