Alien Abstraction

This morning I came by a high rise modern office building in South Miami to walk around. This is the lobby of the One Datran building. It has this huge "thing" and I am not sure what it represents. What looks like a man in a red shirt at the bottom is not part of the structure. It's a real man who walks so slowly I didn't bother to wait until he gets out of the picture, so he became part of it.
