John Carmack is building the future. Well, technically, he’s only helping this time. Along with Palmer Luckey and the other fine folks at Oculus Rift, Carmack’s diving headset-first into the world of virtual reality. Of course, this isn’t the first time gaming’s tried taking Bambi-like first steps onto the Holodeck. But then the Virtual Boy happened, and everyone got really sad. Now, though, Carmack and co are claiming the tech’s reached its threshold for “useful coolness,” and – after a hands/eyes/face-on demo with a duct-tape-and-hot-glue prototype of the Rift – I’m sold. This thing’s the future. Or at least a big part of it, anyway.
