Mozilla Labs proposed the challenge to the design community: "How can we create, navigate and manage multiple sites within the same instance of a browser?”

Our response is Cubezilla, a navigation metaphor based on the Rubik Cube. Each colour represents a group of websites. Yellow could be for social network, green for search, blue for financial, or whatelse the user wants. When the mouse slide over the face, thumbnails of corresponding websites roll down. When do you click on the cube, you can change the face. The face could be maximized, showing more options too.
