World's ugliest buildings?

eek...some of these are pretty bad, but my personal "worst" (from this lot) would be Torre Velasca in Milan, Italy (below).  Designed by the BBPR architectural partnership and built in the 1950s, it's pretty darned ugly!

To counteract these ugly buildings, I'm including two beautiful (in my opinion) and cheery buildings:

Frank Lloyd Wright's Fallingwater http://www.fallingwater.org/
