"Guitar Hero" started with "super-basic "Pong"-style graphics" for the game display. The final game art was led by Ryan Lesser, using the art team's involvement in the music scene. Based on the experience from "Frequency" and "Amplitude", the team realized that "people dont necessarily relate to really abstract visuals", and included the depictions of live performances as previously used in "Karaoke Revolution". The PlayStation 2 was also limited so that they could not do photorealistic graphics. These limitations led to the exaggerated rock art style used in the game. House of Moves were used to assist in creation motion capture for the on-screen animations. The appearance of Star Power was made to resemble electricity, both to reflect the use of the electric guitar as well to conceptually demonstrate the excitement of the performance and the virtual audience.
