Project's called Vanguard Valkyrie and it's a on-rails space shooter with all controlls handled solely through head tracking (very much like Proton Pulse).
I saw his project being mentioned here and there, but I think it deserves a separate thread as I didn't really know nothing about it until I actually went on protonpulse.com to see what's happening in regards to PP.
I already backed the early bird tier :}} and I really like where this is going. I'm only a bit bummed about the high target goal (almost 200.000). Way more than Gallery or Technolust. Fingers crossed..
