I am posting the source to this now as I have a project at work that is going to take up my time over Christmas and into the new year and also have to start studying if I am going to get anywhere with my Microsoft Certification :( I am not going to have chance to add any more to it. So this is the project...

I guess this started out as a bit of a toy. Using my old skybox code, I thought it would be a good idea to have the shader manage the lighting of the sky, you know have like a nice sun rise/set, have the color of the sky slowly change over time. But as I was using a box it meant that you got some corners...
