Prototype #31 is a 31-minute audio/video DVD that fits animated graphics layered on video and TV footage to a 31-minute original audio track. The video is composed of segments designed by C404's Yoshi Sodeoka and invited artists that respond in different ways to the underlying audio track. The project was originally shown as an installation at "Digital Dumbo," a four-day festival held in September 2001, which was devoted to showcasing new digital art. NTSC/Regional code is ALL.
