Abstract: A 3D gaming client in a mobile phone supporting interactive musical video games. Based on beats in an audio input, visual artifacts are created/and presented to the user in a 3D gaming environment. More than one virtual toy character may optionally be employed by the user to navigate and plan a musical video game as the audio input is played. As the user listens to beats of the musical source, the user's selected character(s) in the 3D gaming space encounters corresponding visual artifacts in the 3D visual space. Thus, the user visually experiences the beats/musical frequencies as dynamically created visual artifacts in a 3D environment, and plays a game by navigating to various points in the displayed 3D environment and by navigating over/around the visual artifacts for the musical frequencies encountered.
