Chicago Skyline...oooh

Look at this awesome picture that my brother made. While we were in the city a few weeks ago, we were standing in Millennium Park by the Bean...excuse me 'The Cloud Gate'...and he took a series of photos of the buildings along Michigan Avenue. Then he used his computer savvy and some fancy program (I'm sure he explained it, but I've forgotten) and made this panoramic photo.
Feel free to ooh and aah.
