DAVID COZ WORKED in Google’s Paris office, but what he really wanted was a job at the mothership in Silicon Valley.

Last spring, the French-born Coz turned up at Google headquarters in Mountain View hoping to chat about his latest project with anyone who would listen. “I came with my prototype and my luggage,” he says, “and I met with 10 or 15 people.” One of them was Christian Plagemann, a Google research scientist exploring new interfaces for consumer electronics devices. Though they’d never met, Coz showed him the prototype: a pair of virtual reality goggles made out of cardboard.

Sometimes the best ideas just walk in the front door.
