Musk isn't sharing any of the nitty-gritty details yet, but he mentioned his grand scheme on Twitter. This better not be a joke.
We've seen hints of this tech before—thanks to the Leap Motion Controller and an illusion called Pepper's ghost—but it was all very beta, a long way away from an actual application. The Hyperloop is pretty far from application too. Hopefully this hologram tech is a little closer to finished. How could this not be cool? [Elon Musk via Business Insider via CNET]
