The "pineapple wall," so-called for its resemblance to the exterior of the fruit, on the interior of Plenary Hall (the main auditorium) mimics what's on the outside, and suggests a kind of building-within-a-building scheme for the Convention Center. Due to the massive amounts of glazing, one really does feel that there's an exterior facade as well as an interior one. And continuing that interior facade into Plenary Hall gives the space a real sense of being contained—enveloped but independent.
The chairs in the hall, and there are some 5,500 of them, can actually fold down into the floor, permitting the space to be used as a massive open area for a cocktail party, or, as I suggested and Hamish shot down, a preposterously large ballroom.
