I have just received a long awaited book from Mark Parker entitled "4 E Illusion design". It was apparently "held up"
because of some controversy regarding the first effect in the book called "Revolution". I am one of the few who owns the illusion that has generated the questions and I can assure you that Mark's is a quantum leap of improvement.
There are several other illusion designs presented and they are truly great. There is, also, a section for illusions especially to be performed for television.
There is a final section called "Thoughts on Illusions" which is invaluble as well.
This book is a definite "must have" and I recommmend it unconditionally.
