I just happen to travel to Waterloo every morning but catch a connecting train from there again and never go outside the station.. but my wife does. The IMAX is right outside Waterloo station and my wife told me about big Halo 3 posters that were up at the IMAX. Ofcourse I had to go look and took my camera along. Well she said it was big but I didn't expect it to be THAT big. It's a couple of stories high and goes all the way around the building. Unfortunately the whole building is glass and since my camera doesn't have a polaroid filter or anything the reflection is very bad. It still gives you an idea of just how big it is though.
