Twisting Torso, Malmo, Sweden, 2007

The skyscraper in the back is called the "Twisting Torso," and is actually nothing less mundane than an apartment block, although it's the second highest one in Europe after the Triumph-Palace in Moscow. Completed in 2005, it was designed by Santiago Calatrava, and based on a sculpture by Calatrava that the building's contractor (and ultimately backer) saw in 1999. An interesting story, to be sure.
