Holding device in portrait mode does not work with accelerometer.

I'm not very familiar with your code but what would have to be done to make this work? I like what you've done with this project, very awesome :)

Thank you. A couple quick searches and it looks like it might be easier to fix than I thought! I'll make this a priority.

CMAttitude from the CMMotionManager (for pitch, roll, and yaw) in portrait mode at 90* from horizon experiences gimbal lock http://en.wikipedia.org/wiki/Gimbal_lock. My non-solution was to nullify the accelerometer influence as it approached gimbal lock to avoid a frenetic camera.

implemented transform from (CMDeviceMotion*).attitude.rotationMatrix. works great!

It looks great!
