Aha, I did get it to work with the camera.  But the positions of child objects (e.g. the lights and ground) relative to the parent (the camera) become awry after the last image is rendered.  They keep up fine after that point, and running the script again seems to adjust them correctly.  Do you know what might be going on there?
