"The Cage" reaction

The story seemed to center around the angular-faced young mans eye. Obviously he was an artist who was seeing many things through his eyes (the naked woman, city scenes, etc.) but I was lost when a new man appeared when the eye was free. I think that the eye was originally the well dressed mans eye and when it got lose the man was attempting to return it to its rightful place. I have no idea as to the significance of the African-American man that appears about a third of the way through, nor do I understand why the woman and the scientist wanted the eye so bad. The images of the man walking through the city with the cage on his head were comical and the use of backwards walking was an interesting touch. My favorite part was watching the bystanders reactions as the actors were making their way through the town. My mind is a little fuzzy on the rest of the details as I was starving at that point of the class.
