I like the Arc Lamp.  Bo Concept makes a really nice lamp too; more angular, with a straight shade.

Super cool!

looks great.

Yeah, we really love it.  Great light. Even though its not an original castiglioni, but its a really good knock off.  Check out the whole story at <a href="http://www.grassrootsmodern.com/2006/05/25/happy-birthday-too/">Grassroots Modern</a>

Nice - the lamp really connects the high and low space in the room in a cool way.
