A couple of ideas, probably not even close to original, but I wanted to get them down.
I go for a walk every day, or try to — and I usually take a podcast with me. This American Life, Planet Money, something from the New Yorker, or the NY Times. I’d like to take an episode of Nurse Jackie with me, a TV show. It seems like it would be a perfect application for GG. I could keep my eyes focused both on the show and where I’m walking. (I hope!)
Scoble got a new toy — a drone with a beautiful video camera. While the drone is flying, you can watch it on your iPhone. But wouldn’t it work much better with GG? I want to use my hands to control the drone, and the effect of having my vision being directly wired to the “vision” of the drone would probably be amazing. Esp if it were 3D (which suggests using something like Oculus). It might give you a real sense that you’re flying.
