Grefter,
I also cannot imagine that there's much "behind the scenes" of this exhibition beyond licensing, a couple of images of images, and the statistics behind the voting. Generally, the curatorial "voice" is missing from the exhibition: why, when, and what inspired such an exhibition. That said, perhaps the 'finding' in behind-the-scenes would likely be that voice.
When it comes to creating an exhibition, there is a lot of go-between behind acquisitions, and often a conversation with the artist (this is 'duh', but it's leading somewhere . . . ). It seems as if curators just contacted enthusiastic big-whig game creators and let that enthusiasm speak moreso than an in-depth conversation manifesting visually between however many people involved.
The show could have also benefited from more benches. Saturday was filled with a diverse demographic, but largely dominated by elderly people and young children, the former that wished to stay less mobile. There were. . . two benches for 3 rooms with a lot of walk space. Rant. Just wanted to post this because you're in my thoughts.
