Whether you like gesture control or not, Leap Motion’s fine-grain floating-finger input looks like pure future. And it only gets better when you’re controlling a pseudo-hologram with it. And that’s exactly what Robbie Tilton did with his Tony Stark-worthy setup.
Using a four-sided prism and an illusion known as Pepper’s Ghost, Tilton was able to project a floating globe off the surface of a supine computer monitor and then used the Leap Motion to twist it around with a flick of the wrist. There’s not much more to it than that, but there doesn’t have to be; it’s awesome.
