Vib-Ribbon (ビブリボン Bibu Ribon), styled as vib-ribbon, is a rhythm video game developed by NanaOn-Sha and published by Sony Computer Entertainment. The game was unique in that the software loaded into RAM, letting the player use any music CD to play against; the game could generate a unique level from any track. The graphics for Vib-Ribbon are simple, consisting of straight, white vector lines forming crude, angular drawings of the level and the character, a female rabbit named Vibri.
