A few days ago I tried out an HTC Vive VR device with Google's Tilt Brush app. It's basically MS Paint in 3D. You hold both Vive controllers and have a brush in one hand and your palette in the other. I was amazed how intuitive the controller UI was. Some of the controls are on the back of your hand, but it was incredible how natural it was to pick up and use comfortably. I've never been all that fond of the Minority Report floating screen UIs, but other 3D UIs can feel very natural in the right context.
