To get volumetric textures, you need to use some media. That media also 
need to get enough samples to realy show the structure.

Try this:

box{-5 5 hollow pigment{rgbt 1}
interior{
	media{
		emission 0.2
		samples 15
		density{bozo}
		}
	}
}

You can replace the bozo pattern with any pattern you want. Some need 
more samples.
