When Nintendo wanted to to encourage their customers to register with them, they came up with a novel idea: Let users create a Nintendo desktop.
So Nintendo licensed Object Desktop Lite which includes WindowBlinds + IconPackager + WinStyles integrated together.
And when they wanted to find the top suite designers out there, they picked Pixtudio to create a Gamecube desktop and a Super Mario Sunshine desktop.

In order to obtain the suites you must register your GameCube online. Units sold in Europe come boxed with a VIP 24:7 card which allows for registration online. Once signed up and registered with the special code on the card you can then obtain access to the Super Mario Sunshine theme immediately. It appears the GameCube theme is not yet available.
Congratulations to Pixtudio. They've made it to the big time.
