Great news. I have been dreaming of such a mod ever since I first saw the Johny Lee video. I am very curious to your progress. Unfortunetly I have no programming skills to contribute with, but I would be more than happy to beta test.
I am studiyng interaction design, and I see a huge potential for developing a new way of ineracting with 3d space with this. Imagine a 3d browser (running in CryEeninge2) that you navigate with your own body and head position.
Great work and good luck
Best regards from Jens
