"Smart Sheets" that can self-fold

This is fantastic, a constructed material that can form its self into a variety of shapes based on pre-programmed instructions. It is described as "automatic origami". The technology is in its early sages but is still quite impressive. There would be limits to what you could do with this material as it has to have enough flex points to make a variety of shapes but due to flex points, can only be so thick. Still, very innovative.
