is an application technology which realizes drawing works of ordinary scale on a remote canvas with variable scale and aesthetic sense. The quadrotor(drone with four wings) which flies in front of a canvas has a fixed magic marker, and draws a picture on a canvas with ‘tool of expression’ by responding to hand movement of people who conduct drawing. The work realizes new ideas of breaking away from spaces and physical constraints from which human beings can’t get away from through flying objects which move by mechanic language. The movement realized through programming without spatial constraints shows aesthetic distortion in real time and suggests new direction to movement for creative works. Sang-won Leigh explores physical area and digital area, and combination of human and machine, and researches new ideas regarding reality and human body. The artist recently focuses on combination of mechanical frame containing human’s physical body and computing ability, and on the works showing that human beings transcend a simple sum of genetic parts.
