A work that realizes unprecedented visual expression by treating the different concepts of space, color, and time symmetrically within a higher-dimensional space where they are unified. If each pixel of video data is regarded as a point with spatial coordinates given by 6 numerical values—X and Y for space, R, G, B for color components, and T for time corresponding to the frame number—all pixels in the video can be considered a set of points floating in 6-dimensional space. Applying an arbitrary rotation transforms color gradations, curves, and their changes over time into one another, merging them together, while relationships between points are not destroyed by rotation; at a rotation angle of 0 degrees, it returns to the original video. This work is the latest in the project (as of 2018/2) inspired by the word “dimension,” encountered in conversations with researchers in string theory, particle theory, and theoretical physics during a residency in 2016 at the Kavli Institute for the Physics and Mathematics of the Universe (IPMU), within the University of Tokyo Institutes for Advanced Study. It uses video obtained through interval shooting around the ALMA telescope in Chile’s Atacama Desert.

空間、色、時間という異なる概念を、それらが統一された高次元空間において対称的に扱うことで、これまでにない映像表現を実現した作品。映像データの各画素を、空間を表すXとY、色の混合要素R、G、B、フレーム数にあたる時間Tの、6つの数値を空間座標として持つ点として捉えると、映像中の全画素を6次元空間に浮かぶ点の集合と考えられる。これに任意の回転を加えると、色の階調、曲線、それらの時間変化が、互いに変換され、渾然一体となるが、点同士の関係は回転によっては破壊されず、回転角0度では元の映像に戻る。本作は、2016年の、東京大学国際高等研究所内のカブリ数物連携宇宙研究機構(IPMU)における滞在制作中に、弦理論や素粒子論、理論物理の研究者たちとの対話のなかで出会った「次元」という言葉に着想を得たプロジェクトの最新作(2018年2月時点)で、チリのアタカマ砂漠にあるアルマ望遠鏡周辺でのインターバル撮影で得られた映像が用いられている。
