I have just learned that the art couple Diller and Scofidio (their studio is actually now called Diller Scofidio & Renfro because of their new partner Charles Renfro) have won the prestigious National Design Award 2005 for architecture design. I've written about their Blur Building here.
(N.B.: Notice their web page isn't working. It hasn't been working since at least July. Which goes to show how overrated the importance of PR actually is! - Or is "under construction" an allusion to the architects' never-ending dreams?)
