A short in-camera sequence of play between the filmmaker and a matte box. The inversion of the body is a familiar and natural state in gymnastics, where handstands (逆立ち / sakadachi in Japanese) are an essential part of the physical lexicon. Camera obscuras share a similar state: the image is upside down. In both handstands and camera obscuras, the inverted body is the correct orientation. —Kioto Aoki
