I've just joined the forum because I wanted to share my current VR project, which any of you can try if you have an Android phone. Android Rift basically transforms your phone into an Oculus Rift, and it works pretty well with Condor (I was getting about 20fps with current version, but have some improvements in the works that are already giving me 30-35fps). Your results will vary depending on your hardware and configuration (e.g. HD resolution works quite slow for me, but maybe you have a better router/PC/phone that gets it going smoothly).
It is recommended that you buy/make a headset like Durovis Dive or Google Cardboard (you can get a kit online for less than 10 pounds). But try the app first and then consider the headset.

Please note this is an early test version and might not work with your setup (if you give me the details I'll try to make sure it does), and it requires some tweaking but, as I said, my experience so far has been really cool (I'm really excited with the project). Check out this demo video I made:

I've also tested it with some other games, like Arma 2 and Rise of Flight (there are not that many tracking supporting games). Feel free to try other games you might have. And let me know your experiece with the app!
Finally, I have to say I lost my license for Condor and have to use an old pirated version, which is really disappointing. If you have any idea how to get a new one (without purchasing again) I would be glad to hear. I did contact the seller and the dev support but that didn't help. I can assure you I can prove my purchase with Amazon order (from about two years ago)... or showing myself in a picture with the CD, and the day's newspaper (and a ransom note?

Cheers!
