Yves Behar and Forrest North unveil Mission One, a sleek, powerful electric motorcycle. They share slides from distant (yet similar) childhoods that show how collaboration kick-started their friendship -- and shared dreams.

Yves Behar has produced some of the new millennium's most coveted objects, like the Leaf lamp, the Jawbone headset, and the XO laptop for One Laptop per Child.

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.
