At the end of the GameCube presintation, Miyomato showed us all a wonderful interactive game demo. The demo was very impressive, and the designers behind Pokemon stadium were the creators of this. Meowths Party had many special effects some that include, dico-ball reflections, independent movement of each Pokemon, and beutiful shading! Nintendo proved it was interactive by a Nintendo programmer controlling the Camera movement!
This game is just a demo though, and is not planned to ever come out on GameCube =/
