Vib-Ribbon is a rhythm video game in the style of PaRappa the Rapper and Amplitude. 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. The game spawned two sequels, Mojib-Ribbon and Vib-Ripple, both of which were Japan-only releases.
