Ever played [Myst IV](http://en.wikipedia.org/wiki/Myst_IV:_Revelation)? Most of the game visuals are pre-rendered and you move in a discrete fashion. However, you have the ability to turn the camera 360ºH and 180ºV with your mouse.

I want to accomplish that inside Blender Game using still images renderer in Blender Cycles. What's the most direct, no frills workflow to achieve such thing?
