Pedestrians from Beneath Transparent Plexiglass

Place the viewpoint beneath a completely transparent Plexiglass plane and aim the camera straight up. Show many people walking across the Plexiglass with nothing but pure blue sky in the background; include no buildings. Do not reveal any edges, separations, or boundaries in the Plexiglass. It should feel almost nonexistent. Position the camera very close to the pedestrians while they are actively walking, moving broadly from left to right. Bring the soles of their shoes extremely close to the foreground to create an intense, oppressive sense of proximity from the low upward angle.
