Computer Movie No. 2 is a CGI animation created in advance of video-editing software. CTG programmed graphics on an IBM computer, filmed the screen with a 16mm camera, and assembled the frames as an animated film.
CTG was founded by Masao Komura, Haruki Tsuchiya, Kunio Yamanaka, and Junichiro Kakizaki in December of 1966. These four founding members were later joined by Koji Fujino, Fujio Maruha, Makoto Otake, Takeshi Hasegawa, Shigeaki Iwashita, and Michio Sasaki. With the cooperation of Japan IBM, the group utilized a large-scale calculator and plotter to create cutting-edge computer art. In 1968, the group participated in the Cybernetic Serendipity exhibition at the ICA London, which featured computer art in the context of contemporary art. That year the group also won the 6th annual computer art contest held by the American magazine Computers & Automation, and was featured in the publication. In November of 1969, CTG disbanded; Komura Masao continues his work in media art.
