And I seem to remember there was a topic on grp32x forum about it.
IIRC I even said that 3D cubes are frequently used in logos (GameCube, SGI, NeXT, etc.), so you're fated to see Pandora's logo everywhere
(The cube is used to give a feeling of stability but modernity… I could keep on talking about the meaning of the geometry in logos, but it's hard since I have to find the english terms. Most of the talks about logos on the web would probably be better.)
