shaders?? I just messed about with a double sided shader, here it is, I hope you dont mind but I think it will work with one of the main themes in your composition., the lamp. I didn't get it exactly how I wanted it but it might give you some clues?? anything you might need to know about this just ask. at the end you can adjust the glow with the 'true' and 'false' settings.
take it easy and life will be easy
