This work is an installation with vinyl curtain at the front yard of my school. Usually we do not recognize a space separately. In other words we do not recognize the space in a daily life. But due to the small spatial chasm or a thin layer of vinyl, viewers can start to conceive a different spatial sense. The space which divides into two parts, here and there, leads the viewers to identify both places one of which is in front part of a curtain and the other is in the opposite side over curtain.
