At Spaceworld 2000, after Shigeru Miyamoto showed off a tech demo for a GameCube controller prototype he revealed another variant of the Gamecube controller called the "Wavebird". This Wavebird prototype design looked like a missing link between the design of the Virtual Boy controller and the GameCube controller, having long and slender handles like the Virtual Boy but being much bulkier everywhere else like the GameCube controller. It did end up matching the final design of the default GameCube controller.
