This is my entry for Competition 12 - Real World Reconstruction. A warning for those who wish to check it out: it's a pretty laggy map. If you can't run it in OpenGL, you may have more luck running it in Direct3D. Sorry, but there's nothing I can do about this, it's just the nature of the map.
If you have any queries about it, feel free to ask. Extra info and screenshots can be found here.
