In their recent Mozilla Labs "Design Challenge Summer 09" competition, Mozilla posed the question – "How can we create, navigate and manage multiple web sites within the same browser instance?". Out of the 128 submitted concepts, four "Best in Class" honors were chosen and a "People's Choice" award was bestowed. The peoples choice award went to Faber Ludens for his CubeZilla concept, in which sites can be arranged into equal segments on each face of a cube and rotated, in a similar way to a Rubik's Cube.
