Origami

Origami Technical Apprentice 200 Hours Origami is an ancient art of folding paper. The apprentice learns the few and simple folds that create must common origami. This combined with understanding origami diagrams allows the apprentice to create interesting shapes that resemble various simple objects. The journeyman begins to understand the mathematics behind origami and create the simplest of action origami; which can move in clever ways if the proper forces are applied to it. The master gains true technical origami and is capable of designing and building complex action origami without diagrams. They use what is known as crease pattern design and are capable of mapping out the crease pattern before ever folding the paper.

There are four mathematical rules for origami crease patterns:
 * 1) Crease patterns are two colorable
 * 2) At any vertex the number of valley and mountain folds always differ by two in either direction
 * 3) At any vertex, the sum of all the odd angles adds up to 180 degrees, as do the even.
 * 4) A sheet can never penetrate a fold
