Origami • Perhaps as old as paper itself (105 AD) • Revolution in complexorigami design overpast ~25 years Satoshi Kamiya Satoshi Kamiya

Folding Anything (in Theory) [Demaine, Demaine, Mitchell 1999] • Theorem: Any 2D or 3D shapecan be folded from a square of paper
Tree Method of Origami Design [Fujimoto, Kamiya, Kawahata, Lang, Maekawa, Meguro, Yoshino] [Lang, Demaine, Demaine 2006–2008]
Origamizer[Tachi 2006; Demaine & Tachi 2009] TomohiroTachi • Algorithm to fold any polyhedral surface Tomohiro Tachi
“Self-Folding” Origami “hyperbolic paraboloid”
Kenny Thermal origami[Cheung 2008]
Metal Folding Metal folding Demaine, Demaine,Tachi, 2008
Hinged Dissection[first used by Kelland 1864] • Fold polygons at cornersinstead of lines [Dudeney 1902]
Hinged Dissection Universality[Abbott, Abel, Charlton, Demaine, Demaine, Kominers 2008] • Theorem: For any finite setof polygons of equal area, there is a hinged dissection that can fold into any of the polygons,continuouslywithout self-intersection • Generalizes to 3D
Right-Angle Tetrahedra[Millibiology project: MIT, Harvard, Makani]
