Thanks! I think there might be a couple of different narratives lurking in that photo.
My reference to Sugimoto, for those not familiar with his work,... a few decades ago he made a series of photographs in empty 1920s/1930s era movie theaters where he'd open the shutter at the beginning of a movie. And close the shutter at the end of the movie. The idea was he could capture an entire movie in a single still photo. That's not what I was trying to achieve here, though it had a similar effect in the end.
