This collection of videos includes lectures from Fall 2010 and class sessions Fall 2012. Class sessions are based on the corresponding lectures, and cover submitted questions, clarifications, additional topics, interactive activities, and open problems. Students are asked to view the relevant lecture videos, recorded in Fall 2010, prior to attending each class. The lecture videos and class videos correspond numerically (e.g., Lecture 1 before Class 1, Lecture 2 before Class 2, and so on). The lecture and class session videos are also available an integrated format (synced notes, slides, and video) on Prof. Demaine's website for this course.

    Class 1: Overview

    Class 1: Overview

    This class introduces the inverted structure of the class, the topics covered in the course and its motivation. Examples of applications are provided, along with types and characterizations of geometric objects, and foldability and design questions.

    Lecture 2: Simple Folds

    Lecture 2: Simple Folds

    This lecture begins with definitions of origami terminology and a demonstration of mountain-valley folding. Turn, hide, color reversal gadgets, proofs for folding any shape, Hamiltonian refinement, and foldability with 1D flat folding are presented.

    Class 2: Universality & Simple Folds

    Class 2: Universality & Simple Folds

    This class begins with a folding exercise of numerical digits. Questions discussed cover strip folding in the context of efficiency, defining pseudo-polynomial, seam placement, and clarifications about simple folds and flat-foldability.

    Lecture 3: Single-Vertex Crease Patterns

    Lecture 3: Single-Vertex Crease Patterns

    This lecture explores the local behavior of a crease pattern and characterizing flat-foldability of single-vertex crease patterns. Kawasaki's theorem and Maekawa's theorem are presented as well as the tree method with Robert Lang's TreeMaker.

    Class 3: Single-Vertex Crease Patterns

    Class 3: Single-Vertex Crease Patterns

    This class reviews algorithms for testing flat-foldability for a 1D MV pattern and for single-vertex MV pattern. An exercise walks through determining local flat-foldability, and questions cover higher dimensions and motivations for flat-foldability.
