in order to do it, and then I have no idea what the process would be and how
much light is needed.  In any case, any practical advice on the feasibility
of this project would be appreciated, I have to meet with him next week to
give him some feedback.  He has access to a machine shop and very likely has
the ability to build a good mirror, but as for the rest...
