Best bits of the TARDIS

Since the new TARDIS Design has been revealed, I've decided I'm going to use Google SketchUp to make my own redesign, purely for fun. Honest to god, not for my user series. I have a history of people assuming that when I talk about this sort of thing, it's for my series. Swear to god, it isn't. So what I'm asking YOU is, what parts of the TARDIS do you like? BTW, I want it to be more futuristic looking than what we've become used to in the last few years. So, favourite parts of the TARDIS console room. If I have time I might go beyond the console room, but no guarantees.
