Check out my VR prototype I created this weekend for Ludum Dare 31. It uses the Oculus Rift DK2 and a Razor Hydra.
Unfortunately it currently only works on OSX 10.9+ and there is no gameplay without Rift and Hydra. I might port it to windows once I get the Oculus SDK fully working with OpenGL.
It was mostly a fun project for myself in anticipation of the Sixense STEM system which should heavily improve the tracking quality in the future, compared to the Hydra
You can find more information on the game and the download on the the Ludum Dare Website:
