A fantastic tidbit that popped up in my facebook feed today:

Mahadevan and his team have characterized a fundamental origami fold, or tessellation, that could be used as a building block to create almost any three-dimensional shape, as seen above (credit: Mahadevan Lab/Harvard SEAS)
This comes partially from Tomohiro Tachi, an origami friend, and one of the top people worldwide working with computational/mathematical origami tessellations and corrugations.
If you look further at his Flickr page you can find beautiful examples of 3D constructs and controlled folding mechanisms. It’s very exciting work!
Very, very cool!
