Hidden features on the discs themselves? :O I'm gonna have to Google those suckers and find them all!
Also has anybody got The Casual Vacancy, JK's latest book? I got to the store like 9 minutes before it closed at 9pm on Thursday night just to get my copy. I haven't had the chance to read very far yet but I'm like ten pages in and I'm seeing that it's most definitely a JK-style book already. It even smells like a JK Rowling book... you know, superior? It's also set out exactly like the HP books font and spacing wise. Not that that matters, it just brings up a lot of nostalgia
