In this lecture, I will deconstruct my Peryton model to teach several design tools you can use in your own large grid box pleated designs. Level shifting on a 22.5 degree angle, "free" level shifters, alternate starting shapes folded from a square, and the math of digital lines are the topics of this lecture. We will not be folding the model, but rather, focusing on elements of its construction. Students will, however, receive a crease pattern of Peryton to try on their own outside of class. I recommend students be very comfortable folding complex box pleated models. Also, that they have an interest in the subject of box pleated origami design using large grids (64 x 64 and above). Students will be collapsing small sections of the model which have fairly complex structures. Materials will be provided and no preparation is required from students before class.
