You'll need the obelisk object (here and on Ashundar). Also, I did not include the image mask for a path I was working on and didn't bring to fruition. And...I misspoke about the image map. There is one. Dang it. But, anyway, it's still a pretty nifty setup, if you want to work with it.
When you open the file in TG2, change the Renderer to Quick Render to change the camera. Otherwise you're looking through the path mask camera.
