Acting as a medium between the sky and the ground, this artwork is inspired by airflow aerodynamics and also the qualities of compression and expansion. Common modes of transportation, such as automobiles, trains, and aircrafts, are capable of creating a rhythmic form when they are put in motion. The form of “Movement No.9–Airgate” originates from the impressions of flying, and the broad geometric shapes depict the act of flying. The internal design demonstrates the characteristic of constant motion and brings out a sense of smooth stability with the airflow.
