Call it "tinkering with the top."
These computer renderings show the long gestation period of Donald Trump's 92-story hotel-condominium tower in Chicago -- in particular, the development of its controversial spire.
The seven-year sequence includes the impact of the Sept. 11, 2001, terrorist attacks and Mayor Richard Daley's edict that Trump retain an ornamental spire.
Though the latest -- and apparently final -- version of the spire appears below, the tale of Trump's tower is far from complete.
Because of the tower's scale-shattering height and bulk along the Chicago River, we still don't know whether it will be a graceful urban presence, the ultimate McMansion or some combination of the two.
The expected opening: 2007 or 2008.Copyright © 2015, The Baltimore Sun
