'Symbolic Matrix' forms part of the 'Symbolic Close-Up Trilogy' that dedicates to symbolic notation in Close-Up magic. The volumes, all available on the App Store, are: Vol. 1 - Symbolic Method Vol. 2 - Symbolic Matrix Vol. 3 - Symbolic Cups and Balls These apps blend into the most comprehensive set of technical learning tools for Close-Up magicians, with solutions for mental techniques and notation systems. ‘Symbolic Matrix’ serves to document, draft and study ideas and variations on the Coin Matrix theme. It addresses all Close-Up magicians who dedicate time and ideas to this classic effect, from the early Chink-a-Chink approach to the most recent solutions. Consider the Coin Matrix trick as a sequence of position checks and actions along with dramaturgic and grammatical elements. Pin those down in a most concise way by means of intuitive icons and symbols. Then let them guide you, view by view, to study, analyse, recall, and practice Coin Matrix effects systematically. The ‘Symbolic Matrix’ method gives you a holistic view on the effects, enables you to x-ray the method, and serves to go over your related material from books, lecture notes, brainstorming sessions, and videos. It opens up new perspectives, and is to the Coin Matrix effect what musical notes are to a song. It works on all iOS devices, with the best product experience on iPads.
