I've been watching the excellent The IT Crowd (season 1) on DVD and I think it might be a contender for best DVD menus ever. Not because they do anything particularly new but because of the animation on them.
Anyone who grew up in a world of 8-bit home computers will feel instantly at home, from the "loading screen" onwards. There are loveingly crafted pastiches of Head Over Heels and Jet Set Willy that last for ages. You can just sit there watching for ages. I could anyway. And did.
They're probably worth buying the DVD for alone. Think of it as some great animation with six bonus episodes of a geek sitcom thrown in.
