As part of Australia's largest hackathon, Hackagong, one team has combined a GoPro, Oculus Rift, laptop and Twitch.tv to allow users and the Internet at large to play a human in 3rd person. The wearer sees their world from the 3rd perspective, while the Internet sends them commands which display as overlays in the Rift. Kind of like playing yourself like a GTA character, while the Internet controls you via commands. Trippy af.
