voice.zero (voice dot zero) is a unit launched in 2006 by OTSUKI Kouhei and OHYAMA Sohya (both born in 1985), who sat in front and behind each other during high school due to the placement of their respective names on the class roll. Using "eye copy," bugs, and other methods, they seek to create unprecedented images and visual experiences by using software in their own unique methods. They are active as part-time lecturers at the Tokyo University of the Arts, programmers, and gamers.
