Origami in the 21st century has gone way beyond the humble crane. We observe in nature how leaves and other elements are "naturally" folded up to unfurl as they "grow."
Artists are employing computers (or not) and making fantastic 3-D creations from a single sheet of paper.
Scientists are using it to understand how proteins fold, and creating proteins to block the flu or other diseases at the molecular level.
It's being used in space exploration to fold up solar panels, or block the light for a telescope.
Looking at complex folds to create very strong "walls" in construction. (How about 1 ounce of material holding up thousands of pounds.)
Amazing Origami.
