I would think that having the spaceship auto-orient towards the camera could probably produce an effect that is desirable without the headache of learning Blender. It’d still be a flat plane, but if it’s not rotating about the Y axis, it’ll be a flat plane that faces the camera yet orbits using the 3D coordinates, but we won’t know it’s flat.
But Erik’s right, there’s no easy way to add an affect to make a 2D object into a full 3D object. I recommend going to the Google 3D warehouse, finding a spaceship someone else has made, downloading it, opening it in Google Sketchup, downloading the .obj exporter plugin for Sketchup, saving it as a .obj, opening it in Photoshop, saving it as a .psd, and then opening the psd in Photoshop. Straightforward, right? 🙂
