Views from observation deck of the Chicago Sears Tower - America's tallest building in 2008, but due to be outclassed by Calatrava's Spire by 2012. Sears Tower is formed of 9 tubes, a bit like a Sudoku in plan, each tube a different height.
By todays standards, the building has massive heat loss and is due for a refit to improve energy efficiency. Filmed in March 2008 by DNC.
this will look different in a few years, when the Trump tower and the Chicago Spire are completed. Chicago never stays still. what a great place!
