Swinging Light and ...

I've been thinking about secondary animation in the environment. I've been testing and I've got one working so far. I'm going to get help with the second but I'll update that later when I have it working

The light swing is simple but I think adds a sense of moment to the project apart form the gears in the background. Again they are animated too :D

I would like to sort it out so it actually shines but I haven't been very successful with lighting so far.
