View from under a plane of completely transparent plexiglass. We are looking straight up. Many people are walking on the plexiglass. In the background is a pure blue sky. No buildings visible. No edges or separations in the plexiglass. It’s as if the plexiglass isn’t even there. We are very close to the people. The people are in the process of walking. The people are walking generally from left to right. The soles of their shoes are very close to the foreground.
