A foldable kayak based on origami. OMG, did you see this?

Oru, whose name comes from the Japanese word for fold, makes five models, from the one-person Inlet designed for flatwater to the Coast XT, built for more serious adventures. When fully assembled, the Inlet is 10 feet long, 31 inches wide, and weighs just 20 pounds. When not on the water, the kayak neatly folds into a compact box, similar in size to a guitar case.
