If things start looking a bit wacky around here, it's because I'm upgrading the blog's underlying code. Hence if everything goes splooergy, there's a reason. Bear with me. And yes, I have backed the original design up.
EDIT: All right, on my Macbook at least, it appears to be about 80% of the way there. Most changes, looks-wise, are pretty superficial - like a change to the logo to match the new book. There's a couple of things missing I'd rather were still there, but for the moment it seems to be more or less working.
