....It is hoped that, in the not too distant future, a soldier (or engineer) can carry a can, like a paint can, in his or her vehicle, filled with shape-shifting particles of varying size. By telling the particles via computer what shape they need - for example, a specific size spanner - he or she can make the particles form that shape.
Further down the line it could create clothing that can keep its wearer cool by day and warm by night, or aircraft's wings that can change aerodynamic shape in flight.
