manipulation
got this one covered try the jeff mcbride world class manipulation series mostly stage related manipulations and great advice on stage craft and visibility, a classic one liner mirrors only bounce light once so use a cd.
as for illusions thats a bit harder you will have to take exsisting ideas and scale them up the draw box is a classic example of this, bisexted women anyone
or you will just have to invest in some plans and make up your own illusions.
there was a nice lady on thease boards for a wile who was a stage performer who had some good though at times controversial advice but i havant seen her about for a wile.
most grande illusion's are based on tried and tested basic principles ie what can you see as aposed to what they want you to see.
hope this helps.
