But they looked clunkier than the pair spotted on the subway in the picture taken, by passenger Noah Zerkin who posted it on Twitter today.
Zerkin describes himself as a “wearable computing and augmented reality enthusiast/hardware prototyper,” but told Twitter that he had got into the same subway carriage as Brin by coincidence. He said he had had had “a brief conversation with the most powerful man in the world. On the downtown 3 train. Nice guy.”
