This is a fascinating concept. We’re not sure of its usefulness, but it definitely stands on its own just for the concept.

Oculus Rift dev kits are starting to make their way onto the workbenches of makers around the globe. Some are even going so far as to tear open the hardware and see how they can improve it.
