The definition for skyscraper is a building of many stories. Now, define stories. My first thought is that in every one of these many buildings are people and all those people have their own story. That is not the literal meaning for "a building of many stories". But it fits. Maybe the definition would be better explained if it was a building of many layers, or flights of stairs (no, that brings other images to mind as well), or many floors, walls and ceilings. And there are so many buildings in this image!
The image was taken from the highest building in Chicago as the sun was setting in the west. The light from the sun on the west/east bound streets creates a dimension against the shaded north/south bound streets. This altered version includes graphics, filters, masks and text to add visual complexity and a whimsical edge for the oh, so many stories included within.
