I have to say this has always been my favorite premise.
This is the bible of this effect.
It doesn't include every method but it does have the most practical ones. It is somewhat skimpy
but for the price you are getting a lot of information that has been put to use by the author
if
you have ever thought of putting this effect into your show, buy this. I don't care if you do and i
would rather you don't because i like having this one to myself.
Either way I highly recommend
this book
