Also check out my latest video, a remake of Super Mario 64 using the Oculus Rift DK2, Leap Motion and Razer Hydra:
Mind control and motion tracking in virtual reality with simulations in first person shooting, education and medicine.
Devices used include the Oculus Rift for VR, Razer Hydra for hand tracking and Emotiv EPOC for movement in the environment using thought.
You can read more about the simulation and try it out for yourself at http://vr.chriszaharia.com
P.S. Sorry about the sound and video quality. It was quite noisy outside while filming and we only realised after filming that the resolution was at only 360p as the camera was quite old.
