It is the project of musician and designer Trevor Jackson.
In 2001, Playgroup released the single "Number One", an up-tempo disco dance song.
The music video was computer-animated and featured a tower PC which was transformed into a humanoid dancing robot during the song.
The list included Michael Jackson's moonwalk and the glowing tiles under each footstep first seen in his "Billie Jean" video.
The rocking version of the duckwalk popularized by Angus Young of AC/DC was also recreated by the computer-generated dancer.
