No and no. Sorry people, I don't mean to be annoyingly secretive but if I mention the effect people will immediately get an idea of how it works. Whilst I could also mention what the stuff does it would equally be a case of exposure of a technique. It is only known as monitor foil for this one effect (it isn't foil), I have seen it called other things elsewhere. None of it's names are it's correct trade name. I guess I just need to find out what it is used for in the real world then I'd be able to get hold of some.
I've just realised that this message sounds like a riddle. None of this will make any sense to anyone who hasn't bought the effect so if you haven't come across the term before best to ignore me and put it all down to the ramblings of a mad man.
