I once posted something like, if the TARDIS had the flu and kept changing console rooms or generally rearranging itself in it's fever state, at least we could see some of the old ones.
I'd love to see #4's Victorian console room in the episode where Matt & Jenna are dressed for that period. Maybe the TARDIS decides to dress up for the occasion too.
