What does origami have to do with technology? Apparently a lot. From folding space-based telescopes and camera lenses, to the packaging of your car's airbag, origami is everywhere. Robert Lang is one of the premiere origami theorists and artists in the world. His work has been featured in a number of venues including motion pictures, TV and exhibitions. He joins Patrick and shares his techniques and the mathematic principles behind origami, along with a link to his free origami model generation program Treemaker, which assists users in creating new origami designs by marking out fold patterns and flaps.
