Over the past decade, Yves Behar and his firm fuseproject have become the design group that companies turn to for a game-changing idea. Take the re-invention of the Bluetooth headset, for one; or the re-envigoration of the venerable but dowdy Birkenstock line; or Behar's LED-chic Leaf lamp for Herman Miller.

And yes, Behar and fuseproject are the people who put the green bunny ears on the XO laptop -- and are redesigning the next-gen XOXO laptop due in 2010. This quirky but deeply felt project encapsulates much of his recent work, fusing gotta-have-it design with a mission of social responsibility.
