I may be wrong but … with Cheri’s email mentioning “resulting in multi-layered and unexpected shots”, I am not going to interpret the word Squared as Glass cut into Squares but rather Glass2.
I took 3 shots from different angles of this scene and guess what? No one looked up at me & my camera, no one looked out at the scenery, no one even took a sip of their coffee (or whatever they had) during that timeframe. Each and everyone there was living their own story in their own world.
I guess this is part of the glass-tower lifestyle.
