A new feature for VR development from Leap Motion and Unity allows you to see your actual hands in virtual spaces:
The Image Hand asset is a blend between Augmented Reality (AR) and Virtual Reality (VR). It displays images of your real hands from the camera sensors with the full interactivity and 3D behavior of our classic rigged hands. This works by projecting the raw images of your hands into a 3D mesh that can interact with other objects in real-world space – with total fidelity to depth, intersections and more.
