Van Triest focuses on the human tendency to defuse our fundamental fear and uncertainty with a system. It is an attempt to control the world around us, which comes from a deep need for order, or the illusion of control. This tendency to frame reality in a system or grid is reflected in different levels. It is anchored in our thinking: we divide the world around us into categories and use rational constructions to define differences and make connections. This shapes our world in a concrete sense: from spreadsheets to city planning and landscape architecture. Many culturally determined, applied expressions are based on a linear kind of thinking: the straight line and the grid are building blocks of our culture. His sculptures, often made by hand but designed by devices, plays with the relation between man and machine.
