FYI:
Perrault has a movie (MPEG, I think) on his site that you can download of
the chernetskii tube in action.
Now I haven't actually viewed it, mpeg players are found in IE4 and activex
(or is it directx) movie player are able to play it. Neither of which I have.
Its about 4 mb in size. It might be worth viewing before continuing.
