PS. If anyone can tell me a better way of producing a beam of light I
am open to suggestions.

Currently, I've a cylinder of light in a box with a transparent sphere
cut out of it. The problem is that the documentation implies that the
rays are not parallel so I've not got what I would have thought was a
truer model of a laser beam. Notice in the code that the box is quite
big - that's because I can't seem to get the diameter of the beam any
smaller - and that's why I'm using this box get-up, to be able to
narrow the beam. I tried a parallel light, but the light comes from
the entire plane specified, and so that will not give me a single beam
of light out of box. I tried looks_like (with a small sphere) on the
cylinder and parallel light options and neither wored.
