TARDIS Exterior: Rubik's Cube

Why I went with this design: I think that a Rubik's Cube would work well with the way a TARDIS works, seen as a door could easily be hidden as two of the squares and since the TARDIS spins when flying, as does a Rubik's Cube when being solved.

Great idea it could be its all got the right colours on each side but when you click it to open it, it spins round a little and raises in the air a little and mixes up the colours and opens the door.
