Choi Youngjun is a marine college student, studying machines such as generators and engines. He did not want to become part of existing systems, and instead, wanted to construct a unique system of his own. He thus depended solely on his artistic potential and created Carl. Carl is designed as a VR-based game, and each person partaking in the experience is asked to employ his/her own strategy and plans to derive differentiated movements. The project takes the form of calendars and images of the universe, making it a record of an individual’s personal virtual journey. Choi Youngjun is interested in the potentials of art, technology and science in reinterpreting their roles, converging with one another, and expanding their boundaries.
