[Daily Photo] Reflections on the glass curtain wall building, Chicago

This photo was taken on a boat tour on the Chicago River. The reflections on this glass curtain wall building looked so amazing (like mosaic art). This was my second time to take a boat tour on the Chicago river. It was August, the weather was warm and comfortable for the boat tour. My first experience was in October, I almost froze to death by the chilly wind over the Chicago River.
