Tom in Chicago:
We've imploded three buildings in the last few years: a former city's tallest in downtown called the Landmark Tower, Amon Carter Stadium, and the Medical Tower.
Below are photographs of all three before demolition.

Kevin from Texas:
In several polls, including one on my website, the building has placed in the Top 10 ugliest in the city. I personally don't think it was all that great. In my last photo of the pile of rubble, you can see the city's tallest building in the background, Burnett Plaza.
Rockmont:
Here is the rendering of the replacement building. It is actually under construction to the right of the building demolished.
