Dr. Mitchell R. Zakin is hopeful they can one day build a container that
looks like a paint can and will form universal spare parts or tools such as
hammers and wrenches based on the soldiers' needs, using a building material
they call "mesomatter" that range anywhere from one hundred microns to a
centimeter in size.
I don't know about a "paint can" necessarily, but imagine the possibilities of being able to transform some innocuous material into something you need? What about the applications for building homes in the future? Or prostheses? Go-go-gadget legs!! ;)
Now that's just too cool for words. DARPA rules!
