People have been using 3D models for 2D graphics for at least a decade. 3D models rotate, by default.
This demo shows generating a 3D model from a simple 2D shape. It'll fall flat on its face trying to 3D model anything non-trivial which begs the question - who cares?
Also, you'll want to animate the 3D model - which this doesn't do, so you'll soon be back to your usual 3D toolkit anyway.
