Hey! This is a video of a GameCube tech-demo. It was released to show the power of the Gamecube to developers and was included in early versions of the Dolphin SDK. The demo shows off effects such as bump and shadow, local lighting and Anti-Aliasing.

At 5:36 you can see an unreleased pink Gamecube.
This was running natively on the Wii and music you hear is from the demo.

More info:

The tech demo has 2 modes, normal and auto. For this video I showcased the manual mode and this is where you can control the arrow. In auto mode the demo plays like a video, going threw the different rooms. You can also access the debug settings and change the how the GameCube renders the game and more!

Thanks for watching ;D

If you wondering what that blue and red bar does, it shows you the CPU and RAM the Cube/Wii is using.
