This has been posted many times. And each time, I never truly understand what's wrong with w3schools. I used it when I was much younger (although I've switched to MDN now) and I haven't found very much wrong with it. Can someone please enlighten me?
At Greylock HackFest two weeks ago, someone built the Oculus Drone (https://github.com/feross/oculus-drone) which was a quadcopter-drone that could be controlled by the Rift. The Rift would see what the camera mounted on the drone could see. I think that made for an awesome experience!
