shifted the turntable to match the location of the camera so the perspective effect is less dramatic. and "stretched" looking.
bug: Portrait mode still doesn't use orientation.beta properly since tilting upwards or downwards is an absolute value
Best compromise: portrait mode lets the forward view actually be downward towards the floor. I guess this is what apple wanted? Weird.
Both landscape modes look beautiful with complete tilting! Woohoo! :D
Just don't try to turn the phone up-side down… :/
