What if you could cycle through different themed lighting settings for the Tardis, like Black and White (for the classic Tardis interiors), Coral Lighting (to fit the coral interior better), etc. (Imagine some others  ).

This system could be a sort of filter that would change the look of the actual game on the client side while in the Tardis maybe even allowing for people to make custom themes.

That would be fun. I suport this idea 100%. (I am not joking. I like it)

It would also be nice if the exterior windows adjusted to the interior lighting.
