At Spaceworld 2000 during the unveiling of the GameCube, there were five models that came from backstage each one holding a uniquely colored GameCube, the hot pink color never seeing an official release. Each GameCube featured a small window cut into the jewel (black circular disk atop the GameCube) allowing for the player to see the disk and disk tray. These prototypes do not actually function as they were made just to be shown at Spaceworld 2000.
