There is more to it than that, Christian.
Imagine a simple box materialising. Do we want to see the hidden faces as it
goes from transparent to opaque? With a model of a police box all the internal
and hidden detail would show. If a person went from invisible to translucent to
visible, would you see their body under their clothes and what about all the
internal organs?
Now with a Tardis how do we see that the inside is larger than the outside?

100 Karma points to the person who can do a realistic (WTF) materialisation or
de-materialisation of a complex model. (With shadows and you get 500 Karma
points.)
