Hi Wingnut
I have viewed your demo and it not helpful for me.because i want to change camera position with rotation effect.
I can explain you in detail with your example,When you rotate your box and after that click on "setDefault" button it jump on default position without any effect,see below video link.

I want to use same rotation effect like in Microsoft Xbox.When you rotate Xbox remote multiple times and after that click on back button then it change camera position with proper rotation.
