Gallifrey:

Planet of Hats.

Actually, more assorted DW related remarks

I've been watching the last season of Ten and I'm also in the middle of the third season of Four, and here's some random stuff I've scribbled down on a scrap of paper:

Timelord writing. Nice. Especially the letter that looks like a little mouse, complete with tail and teensy round ears. (The Deadly Assassin)

The Doctor - in Gallifreyan formal garb, no less! - doing small talk with an old classmate: kind of brilliant. (The Deadly Assassin)

I don't know why, but the copy of Ten is sexier than Ten himself, whom I don't find particularly sexy. Oh, wait. I do know why: he's wearing a t-shirt. (Journey's End)

The Doctor wouldn't say no to a salami sandwich... best moment in The Masque of Mandragora, bar none.

In terms of looks, the Fourth Doctor's secondary control room is the direct ancestor of the latest two versions of the Tardis control room, I think.

I am so grateful for the Tardis Index Files wiki.
