Parimental | Jheff Goldman The spectator sets the clock's"This is a fascinating work and a tool that supplies the reader with an abundant supply of new and usable material Self working effects, based on clever mathematical principles are often a relief to perform and give you ability to concentrate fully on your presentation. Parimental explores just one such principle with some 20 different effects to choose from along with some very sound presentational advice." From the Foreword by Richard Osterlind
