When I was young child, I was playing with the toy of dinosaur, and robot at my apartment house, after a while, I had minor fiction related dinosaur, robot image. Due to the fiction, I had strange laugh. Due to the laugh, I estranged from the surrounding ones. So I look like to monster robot, that is wrapped loneliness as accumulated emotion from the past. Due to a sense of alienation, I express ‘apartment’ image for escape to a world of my own space, And ‘my smile’ image for return to a childhood memories. The image of apartment, dinosaur, and my smile are combinated in one of the robot. I express a sense of alienation and psychotherapy of childhood regression with matiere technique.
