Just wanted say thanks to the devs for implementing this feature!
For those that don't know - It allows the video to zoom in slightly when you move your head forward, out slightly when you move it back and I believe it pans when you raise/lower your head. One of the things I don't like about 3d movies is when you lean forward and the entire video seems to move away with you. This fixes that!
Very cool, keep up the great work!
